I'm upset that my family thinks I'm high maintenance
Why do they think you're high maintenance?
I just wish they wouldn't have told me they think that way.
Family comments can hurt a lot and it's okay that it bothers you that you were called high maintenance. Talk to them and ask why they said it, let them know it hurt your feelings.
Mom sucks. She's just jealous that I'm getting married.
Well no matter the reason, you should talk to her and tell her why you're upset with her.
