sometimes it feels like i will be never become a person what i wanna be in past....my time is ruined

So i started to feel like a lesbian again and that i have to be one. I dont want to be one. I just dont. But being straight feel like a lie now. I question my whole life, my feelings and everything. The biggest indicator of this must be that i will be slowly 21 year old and ive never dated anyone and i dont really find anyone attractive and i dont even know if i truly was attracted to someone and im scared of relationships i might have trauma or have anxious avoidant attachment. Help me. I do feel lost. Really lost. I dont know who am I anymore. I feel like that i must have been gay my whole life now. I feel like an alien. I sometimes feel like 2 people are living inside of me.😞😞😞

I miss when I wasn't ruminating 24/7, waking up with horrible anxiety or spending all day doing compulsions. Even when I try so hard to resist them I just end up in a spiral. I miss when I was comfortable in my nonbinary identity and didn't have TOCD and now everything feels wrong and conflicting. I miss when I wasn't depressed and disabled. I know I can never get that person back. I haven't seen that person since high school. Ive spent years with this disorder and i havent gotten better despite therapy and meds. I don't know if I'll ever be happy again.

will i ever be free or is this all there is for the rest of my life
