I'm worried about being alone forever

I'm sort of new here and I guess I just wanted somewhere to vent.I'm 23 years old, part of a culture where being gay is highly frowned upon and recently came out 6 months ago. It was okay but right as I came out my two-month relationship with my first boyfriend ended due to things out of my control and I got disowned by my mom. I've more or less recovered but part of me misses the feeling of being wanted by somebody.I've tried dating other men but every time I get the same result. It doesn't get anywhere, like me being who I am isn't good enough for anybody anymore. No responses for second dates or anything. The fact that I spent so long by myself, only to have a glimpse into what it was like to be in a caring relationship and then having it snatched away from me so shortly still hurts.I stay up all night worried that I'm going to be alone forever, that this one person who couldn't handle me being honest with him was the only person for me. I know this isn't true and there are much better, more compatible people out there for me but the fact that nobody wants to stick around after the first date is really disheartening and playing games with my self esteem. Like maybe I'm just destined to help others and not be loved on my own, even though everyone else tells me otherwise.I just don't know what to do. Sure, I guess every other aspect of my life is thriving but seeing others around me who fight and make up with their SOs while realizing that I never got that second chance just hurts. Like I'm worthless...and will remain alone for the rest of my life.
