I am an orphan. I have no parents, no family. I was in a long term relationship where I thought I might finally fulfill my wish of having a family, but I now see that that will not happen. I feel so doomed to live a life without family, when that is literally the only wish I've fought for...
What do I do?

You keep fighting. I'm in a similar spot as you, all I've always wanted was a good relationship and a family. I thought i had the beginnings to that with a gf of 4 years who recently broke up. So now I'm 28, single and confused. I live in a very small town and I feel like there is literally noone in a 50km radius that either I would be interested in or that would be interested in me. But I keep fighting, cause that's all you can do.

You might find another relationship and chance to build a family. Or later you might realise that it's not as important to you anymore. Or you might realise that you've found family in other places - friends, pets, etc. The point is you should try not to worry too much about it (which is easier said than done).

I agree, keep fighting. Family is important to me too and I so want one of my own one day. You know the nice thing? There are so many options in the modern world. You can choose to be a single mum, you can get a donor or adopt or IVF, so many options and no one is going to judge you for wanting a family. Partners come and go and so when a new one arrives make sure to ask them if they ever want children in there lives, cause if they don't then it's going to be very difficult in the long run to maintain that relationship. You'd be surprised how many people are in a similar situation to you, you have to think creatively and try and stay positive, a family and happiness doesn't have to be created through conventional means.

So, I know its easier said than done, but you can join an existing family. I have one friend whose mom is Mama in my phone. I've talked to her mom about issues in my life when I felt I needed guidance. I've picked her sister up from school and driven her brothers to work. They are family. We exchange Christmas gifts every year.
If you can find people who are willing to make you a part of their lives and you want to be a part if theirs, that's how you make a family. You just have to be willing to support each other. I know finding those people may be difficult, but it doesn't require a romantic relationship. I wish you the best of luck.

Thank you all for your encouragement! I hesitated posting this very un-fun thing to a site where people look for entertainment, but seeing your replies makes me happy I did.
There are many ways to become part of a family, or to create one. I am starting to feel too old to manage, but I have no other choice but to try and try again.
I've come to realize that my partner, who I've been with for 10 years and who I thought I had the beginnings of a family with, has never seen me as a long term option. Which obviously came as a huge surprise to me after having been together for 10 years.
I have been with him since I was 25, and thought we would have a family together. He knew how much I wanted to be part of a family since I have never had one, and he has strung me along with the promise of one for 10 years. I don't understand how someone can be so cruel.
It's fine. I'm incredibly disappointed and hurt, of course, but I will keep fighting. I know I shouldn't compare myself to others...

...but I can't help seeing so many people with a mom, a dad, sibling, uncle's aunt's. etc. etc, and feel a pang of loss and longing.
I want that soo bad! I can't understand, why my partner, who knew my wish would just lie to me for 10 years and thus keep me from finding my life-long dream.
It's ok, though. I have been alone all my life, and I am OK. I will continue to be alone and keep looking and fighting to find a place with people who love me and will see me and treat me as family...
Thank you again for all your encouragement. It has meant a lot!

@lihea I know your feeling! I‘m going through something so much similar right now. I lost my mom when I was 6 and my dad is messed up in lots of ways. He has been estranged from us and has generally been very abusive and dangerous from the very beginning. He really doesn‘t care if we are alive or not. I can say that I‘m equivalent to an orphan since both my parents are not in my life and my entire well being is handled by other people I don‘t really know. When I left my dad‘s, it felt like I stepped into a new world. I wanted a place I could call home(a feeling I have never experienced). I put so much hope in finding a home in my mother‘s side of the family, but I had been away from them for too long that I‘m just an “extra“ to them.

I tried several times to feel that belonging but it didn‘t work. Most of them don‘t value me. It makes me emotional when I see how happy people are with their parents. Even if my mom‘s family didn‘t work out(in your case, your relationship), it doesn‘t mean I‘ll never have a family or a home. Every single failed family relationship I went through, I learned something new. First of all, the happiness you want first begins with you. I‘ve made up my mind that I don‘t have parents and I won‘t let that make me misreable. No matter how much you want a family or to be part of one, don‘t let it push you to the wrong people because they will try their best to suck out all your hope and all your joy. Don‘t be in relationships(in general) with the hope that this person/people will be your dream come true if they don‘t value your presence or who you are. Even after everything that went wrong, ‘NOs will never be equal to NEVERs.“

@lihea About your 10 year relationship being a waste of time, I was incacerated for about the same time by my dad. I missed so many great opportunities and I would‘ve achieved so much more. But what‘s done is done, we may not be able to get back our ten years but it does not mean that we should let that make our remaining years misreable. As far as you are alive, you have hope and that means that your dreams will definitely come true. Now you‘ve known better and learned a lot, you kno what to avoid. you will definitely have what you want if you don‘t give up. I believe that. It‘s time to move on. One mistake I will never make is go back to my dad. Don‘t attach your happiness to people. I bet you‘re an amazing people. Keep being that. Good character makes a person a lot more attractive.

@ Aviva
Thank you for sharing your story with me! I'm sorry for all the stuff that has gone awry in your family life and how disrupting those things must have been during your childhood.
I love your attitude, though! You're right, as long as you're alive there is hope for something better as long as you keep fighting and don't give up!
I will keep looking for better and keep looking for people who love me and will see me as family, and barring that, I can become a single mom.
It wasn't my dream to become a single mom, but it has always been my dream to adopt and luckily for me it's currently rather easy for financially stable single moms to adopt.
Whatever family I will make, however small, will be a dream come true.
Like stitch said:
This is my family. I found it all on my own. It is little and broken, but still good. Yeah, still good.

@lihea I‘m fine :)
And thank you.
I know you‘ll definitely find what you are looking for. I do hope thay whatever you decide to do positively works out. And Stitch‘s quote reminds of “Ohana means family“

@lihea Adoption is wonderful and there are so many children who need a parent as caring as you. And even if that doesn't work out, never discount being the lovely lady down the street who bakes cookies for the neighbors, gives piano lessons, and always has a kind ear and a cup of tea. Family can be as small or large as you want, even a whole community.

If it's any consolation @lihea, you're already a part of this family. Blood isn't what makes a good family it's the bond between the people.
