Please help! Don’t know what to do

So I’m afraid I am gonna be alone for the rest of my life and most of you probably will think I’m dramatic and that’s okay I get it. Think what you want. But I’m 20 never had a boyfriend and only two guys have ever talked to me but that was like 3 years ago. No one is showing interest in me and I have put myself out there and keep getting rejected. Is there something wrong with me? Am I doing something wrong? I’m just lost and I think I am starting to lose apart of myself.
