I seriously can’t do it

Loneliness starts mostly with yourself. Look at yourself, would you like to spend time with yourself if you were someone else? Why is that, how do you want to change. Tty to work on yourself first, someone once told me "if you can't stand yourself, how can others?" So try to be the best version of yourself, someone you can be proud of. Do small steps, documents your goals. It always takes time. So don't rush it. You got this!
