I know plenty of single people of both genders. No one cares. I've never seen anyone shaming anyone about singlehood. Why do you worry about nonsense?

Seeing a therapist might help. Or actually seek proper diagnosis.

Is it possible you have OCD? I am not trying to diagnose you but making a suggestion.

You are allowing this obsession over who says what on the internet consume your life. These are anonymous forums. They aren't your friends or family. It's just internet. Get out there. Get to know people. Enjoy life.
