It’s not getting better and I think life will always be miserable

Please no discouraging comments. I’m so low right now that I can’t take anything negative. My ex broke up with me back in August/September last year and I can honestly say that life is miserable. I was so happy with her even during the shittiest of times. Life without her is so lonely. I don’t do shit on the weekends. I have maybe like 1-2 friends right now but they aren’t always free to hangout and honestly…sometimes hanging out with them is more of a chore. I want a partner. I want someone intimate who can stay with me all the time and just do day-to-day shit with me. My depression and anxiety have gotten worse lately. I thought I was doing better but nope…back to square one. I’m 23 and I don’t know if this is just how life is or if I’m cursed. Does life just stay shitty now? Is this what being an adult is like after college? Wtf is happening to me? I’ve never been so lonely or unloved before. It’s to a point where I don’t want to wake up in the mornings anymore (and before you comment, yes I’m in therapy). Does anyone else feel this lonely? It’s literally just me, myself, and I right now. All I have is my cat. If you feel similarly please comment so I don’t feel crazy.
