I’m so lonely

I’m so sick of being alone all the time. My sister has moved out, my “friends” only want to see me when it’s convenient for them, my mother is constantly drunk or angry about something. I’m so sick of it. I cant bare this loneliness. Any time I stop and think about the things that are good in my life my mind goes completely blank because there is literally nothing. I’ve lost all hope for the future. People always tell you “you’re young!” “You’ll find your place/people eventually” “give it a couple years” but you give it a couple years and it’s all the same. I used to dream about being this age and how much fun I’d be having but it’s all miserable. I try so hard to keep a happy face, never cause conflict and never let people know what I’m feeling but I just can’t bare being this empty and alone. I’ve tried therapy and it didn’t help, I’ve tried counselling and it didn’t help, I’ve tried talking to family and it didn’t help, I’ve tried making new friends and I cant. I genuinely think by some cruel trick of nature that some people truly aren’t born to live good lives.
