Just clearing my mind

So excuse this, but I feel like I have no one else to talk to and I'm feeling really low.

I moved to a new UK city last summer and despite my best efforts have struggled to find or make any new friends. I'm feeling so alone and lonely and, despite dating a few guys, nothing seems to be sticking. It's sapping away at my motivation to do anything after work - I just eat, watch stupid shit online and fall asleep.

I get really depressed because of all the things I used to do - sing in choirs, hang out with friends, go for walks and adventures - and I feel like the months are slipping away and I'm not achieving anything.

My friends from home are now either a) off working somewhere else so I never see them or b) have problems of their own like illness or bereavement so I feel I can't share with them.

I want to be happy and successful and motivated and busy but it's just taking one small thing to completely throw me off balance for a whole week. If anyone has any ideas on what to do, it'd be much appreciated.

I'm a 20-year-old guy.
