i find it hard to make friends?

[eddielola]

I'm not very confident, i have a lot of self-image issues, and find it hard to trust people. Growing up my friends weren't very nice to me and it has really affected me in the way that i'm afraid it will happen again.
Even now, i find the couple of friends i do have only see me when its convenient for them, when i want to do stuff with them they're always too busy, but i'll always bend over backwards for them when they need me.
I don't know why people don't like me... I'm a nice person, fun to be with, and a really good friend.
I don't have any interests or hobbies to help me make any friends, i just really enjoy working a lot to stay a little social
but the people i work with are much older than i am, so don't spend any time with them outside of work.
what's wrong with me? what can i do to make more friends? it really gets me down to think that i only have 2 friends and i'm 25 years old
