Have you been to a physician that recommended you game anti-depressants?

yes.

Tell her you want to start with talk therapy and let the psychiatrist have the conversation with her.

My parents didn’t believe in my mental illness. I had to wait until college to receive therapy and meds.

Well you need to have a doctor check you out and then go to one of those tests to have proof of your illness, then you can ask for medication, but I really suggest getting your therapist (or getting a therapist first) to talk to your mother if she doesn't believe you.

I second the therapy option. It's good she's cautious about anti depressants, especially if you're in developmental years (and you should be too, as should any therapist you see). I think if you can at least establish an on-going therapy routine that's at least a foot in the door, and keeps you from having to deal with this in a way that entirely feels like on your own. It's not idea but it may be the best way to convince your mom there is something deeper going on. It may also help to see if there are any mental health seminars or such going on near you guys and see if your mom would be willing to go

This may sound like I'm trying to be a villain but please don't take it that way, depending on where you live psychiatrists just throw out meds left right and centre and it's pretty damaging. They should be the last option as it takes a lot of trials to get a medication that works for you and sometimes during this process the side-effects aren't worth the payoff. I would recommend doing a lot of research before you even consider starting them, talk to your psychiatrist, ask them questions and then either relay this information onto your mum or organise a chat with her, you and the psychiatrist. Depression isn't an easy fix and I'm not saying medication shouldn't be an option but it should be a last resort cause the last thing you want it to become reliant on meds at an early age, which sure, may make you feel better but they don't really fix the problem in the long-term.

It doesn't seem like anyone commenting is a psychologist so here's my take: Your best option is to have your mom meet with your doctor so she can hear it from an expert. If she won't listen to them, then nothing you do will convince her. Find out how old you have to be to consent to medical procedures in your country/province/state. It may be 15 or 16, but it may be different for surgery vs medication. If you're of legal age but just worried about ruining your relationship with your mother, screw it - your body needs medication just like you would need insulin if you had diabetes. Anti-depressants DO help in the long-term, because they solve the chemical imbalance in your brain, making it function normally. Medication combined with talk therapy is your best chance at successfully treating depression, and your family preventing you from getting care is actively contributing to the problem.

Unfortunately both @parisqeen and @unicycle are sort of right here. The fact is, some doctors do use pills without enough caution. However, depression is a chemical issue that in many cases requires medication to treat effectively. Medications should not be a last resort, but they should be approached with some caution. If you suffer from clinical depression, you probably will benefit from medication. My best advice is to start with a low dosage, be as open and honest with your psychologist as you can be, and take your medications are prescribed. Usually this approach prevents any really terrible side effects from really negatively affecting you, but catching them when they first appear.
As for your mother, I think your best bet is to talk about her concerns in a way that respects her and her concerns, no matter how misguided, while still having firm expectations. This should be easier if you have the right to your medications without her. It's not foolproof, but its something.

Sorry, I didn't clarify that yes there are many different types of depression and unfortunately if yours is chronic/genetic then medication is the main option. I just presumed it wasn't genetic as usually doctors are aware of your history, so sorry for the assumption. My main point was don't rely on medication to fix the 'source' but if your source is literally your genes then there's not much else you can do. Like @unicycle said, always coincide medication with a psychologist or some form of person-person therapy. Anyway's in the end if your mum has your best interests in mind, she will be willing to listen to you, I hope.

Unfortunately even if your depression is genetic, history of stigma against mental illness has meant many people who suffer from mental illness denied it rather than getting help. This means you could have a undocumented family history really easily. That's not a reason to immediately throw drugs at a depression patient, but it is important to remember.
Also, I hate to have to point this out, and I genuinely hope your mother can be reasoned with, but having your best interests in mind and even at heart does not stop parents from being bad for you. Most anti vaxxers genuinely believe what they are doing is best for their children, and have their child's best interests at heart. That doesn't stop them from making terrible decisions for their child's health. If @llamas0can0fly has a mother who genuinely believes the medication will be bad for her child, she may not be willing to hear otherwise. And, again unfortunately, the side effects of many medications can be awful...

And there is a history of meditations that did no lasting harm to patients. We try to do our best to avoid that kind of thing, but it's fair to say it hasn't helped people's fear.
And finding the right medication and dosage can be a hard process that often does have temporary side effects. When I was suicidal my doctor put me on abilify. And a low dose helped a little, but not nearly enough. So she upped the dose (from 10mg to 15mg. It's the smallest jump you can really make of that drug) and my depression was helped, however my anxiety jumped so high I couldn't function.
I work with a woman who takes abilify in the evening because it helps her not have nightmares. It's not a bad drug, but you still can have bad reactions. And the process of figuring that out is not an easy one. And one that often leaves people believing that medications are bad.
I'd like to believe your mother will respond well to being educated on the matter by a professional. I just wouldn't expect as much.

Thank you for all of your help. I hope it works

Keep us updated if you'd like! Good luck <3

Hi.
By the time, I am replying back, I hope your mom got convinced. Anyways, you should not tell her straightforwardly that you want to take medications for your depression and give her time to decide that. Let her gauze the intensity of your problem by the psychiatrist's intervention. I hope she would understand. Also, anti depressants are not the only way. Other therapies include one to one counselling and family therapy. Maybe you should talk to your mother about it and help her gain a better perspective of your problem. My only advise would be to give her an array of choices rather than telling her about one option constantly.

We have decided that getting me medication is best. Thank you everyone for your advice!

Fantastic! Keep in mind that some side effects are normal and will go away after a few months, but don't be afraid to talk to your doctor if the side effects are unbearable. They can help a lot by adjusting the dose or changing your medication but only if you tell them!

DEFINITELY talk with your doctor, closely. Meds can cause lots of side effects and it's important to let your doctor know so you can sort out what works best for you

I'm super happy your mum agreed, well done. I hope you start feeling like you're improving.

Do remember, the first medication isn't always the right medication. If you don't feel any better, be honest with your doctor about it. Finding the right thing can take a couple tries, but it will get better
