Read about red flags, I have those red flags...

You know how to realize whether you are a good or bad person?
By listening to others complaining and ranting about people, they will mention flaws and red flags, and you can then know if you are good or bad person.
Even if I'd got a relationship tomorrow, I would be full of red flags: not hanging out with friends, not having hobbies, not having conversations, clingy, insecure, etc.

I don't know how to fix all those things, one day I'll do some exercising programme, the next day I'll be munching on some junk food, and I have no personality, no discussions, nothing at all...

I'm bound to be alone, I don't even know if I should try anymore.
