What do you do if nobody wants to talk to you?

Look before you tell me things…

I regularly go to gym but I do it alone.

I shower regularly and I do have quite an OCD for hygiene.

I take fashion quite seriously whenever I go out, whether I go for something classy style or streetwear. I like fashion.

I just dont talk alot. I dont know how to start or make a conversation. Usually when I try nobody reciprocates so it’s useless.

I might be ugly or plain although there are like way uglier and meaner people out there who’s got it all well. I just couldn’t fathom.

Im a loser and I cant accept it!

Please help or give me some advice to understand what did I do to deserve all the humiliation.

I felt like im the only most hated person in the universe.
