Getting a supportive boyfriend might help, my ex helped keep me happy when we were dating

Have you tried going to a therapist? It's not always what you think you need, but they really do help.

Dear @lilithbelatrix,
I wrote an answer but it was too long to be posted here, so I made a note online, here is the link: http://notes.io/irfD
I really hope you can find something helpful, please stay in touch with us!

Keep going to class or work or whatever. Even if you haven't showered, even if you're in your pajamas, show up. Having a routine can help you feel more like a person. Reward yourself for the little things like getting out of bed or taking a shower, but try to push yourself to do more if you can. Specific, achievable goals are the way to go; don't tell yourself "Take a walk today," instead try "Take a 15 minute walk after lunch." Instead of "Eat something" and "Talk to someone" try "Eat some eggs and toast for breakfast" and "Text [name] to see how they're doing." Having supportive family/friends around can really help, but if you don't you might want to consider therapy. Of course eating and sleeping are important, and be aware of eating/sleeping too much as well as too little. So many of my patients feel like nothing's working for so long, but then they find something that does work and they start getting better. So keep fighting and trying to feel normal and eventually you will.

Thanks for the answers guys, I've been doing most of these things ie. Keeping bussy, going for walks and trying to spend time with friends, but I suppose if I carry doing it for a few more months it may work. Xx

@thedarkknightess, @dimebag, @unicycle, I have therapists in the past, but it really didn't help much.
@communistcorrector dating does not appeal to me.
None the less thank you for tour thaughts on this. Xx

Sorry I know this is a late answer but getting a psychologist or psychiatrist really does help. It took me 4 goes to get the right one (might take even more) and on the 3rd go I just thought no therapy like that would help but I eventually found someone who I could just talk to and who gave me ways to cope. Death is horrible and I'm so sorry your nana passed away so it's completely understandable you feel this way. I suggest keeping a journal, really try to get inside your own head and figure out what thoughts your having because thoughts can impact on your emotions very easily. Treat yourself well, take time out to just be with you and you alone, watch a movie, take a bath just do something you enjoy. Try to stay active, and not just walks but really push yourself to help release dopamine and endorphins. Most importantly talk. I can not stress how important it is, no matter how hard it feels, just talk to people. If this is too difficult find another way to release your feelings like

painting or singing etc. This feeling might stay for awhile but don't let it manifest. You want it to go away and you're asking for help which is GREAT and that's awesome you're aware of how you feel. We're always here for you if you need to talk or more suggestions but you're never ever alone. x

@parisqeen Thank you for the reply and support.xx

Absolutely no problem, always happy to help x I hope to start feeling better soon

I know the feeling. The day my grandpa died, I felt like a part of me went with him. Sometimes you just have to remember the good times and hold onto those, rather than think of regrets. Not to mention the fact that your Nana may not want to see you this way.

Antidepressants have helped me stabilise my baseline happiness, and therapy has taught me a lot about how to recognise, and deal with, the triggers and suboptimal mental habits that were contributing to persistent conditions of pessimism and crippling victimhood. You've asked for help, that's a huge step in the right direction - but random internet people are a resource of limited usefulness: get professional help. Decades of training and experience are valuable in all sorts of ways that we simple normies cannot hope to comprehend.
Also get lots of exercise!
Good luck and don't be afraid of the hard work ahead of you. It's worth it.
