No one wants to be my friend and I don't know how to fix that

Can you join a club?

The thing about that is instead of trying to extract something from people you should do for people instead. Expect nothing in return ever.
The pain you feel can be a good friend. The reason for that is it can make you strong. I've been where you are in a way. An abused kid kept isolated in shacks and old trailers along the road. Nobody wanted anything to do with a thing like me. I can't say I blame them. Coming from that I was never going to be right. I just kept to myself I read books I thought constantly about life as I wondered in the wilds. I adapted. If I had fell into despair who knows. I might have given up. Maybe turned into some junkie loser and went to prison like a lot of people. It's OK if you don't have friends or a boyfriend or any of that stuff. Lifev is exciting and full of all kinds of pleasures. Some people are not like others. There have always been monks and shamans. People like that aren't intended to be part of the crowd. Believe you me. Starting out where you are and from what I'm seeing here who knows, your life could be a hell of a ride.

Why do you feel worthless because some girl ghosted you?

Do not think like that - you are special and you have your own identity.. do not wait for other people's approval in your beautiful life.
