Scared I’m going to be alone forever

Literally no one wants me. I haven’t had an emotional or mental connection with anyone since I was 19 I’m 21 now. It’s not hard for me to get a guy. I’m pretty, funny, and smart. It’s not me bragging it’s just the truth. Bc I know what I bring to the table. But every guy I come across it’s just a waste of time. Bc it never goes anywhere. I’m just feeling very down right now bc everyone around me is happy and with someone and I’m not. Idk what I’m doing wrong.
