I'm unhappy with my girlfriend after she made me tell something to my parents that I didn't want to.
What did she force you to tell your parents?
She made me tell my parents that I'm crazy.
If your girlfriend was legitimately concerned about your mental health, then her actions are understandable. But it is concerning that she would force you to tell your parents things that you do not want to tell them. You have your own agency.
Whatever, it's okay. I'll just keep yelling at her about it until she gives up on life.
What she did was not fair, but you should not want her to cry and give up on life. Next time, just discuss with your girlfriend what the boundaries of your relationship is.
