Oh my goodness I think you got scammed.
I won't loan anyone money. If they ask, I'll inquire what they need the money for. If it's something I think they need to survive, I'll take them and buy it for them.
Join groups or clubs that involve your interests. That way you hav at least one thing in common with the people there. Other than that since we can't see you interact with people we can't give you any guidance. Ask a friend or fanily member what you can do to fit in better.
What do you identify as that makes you socially rejected?
