Thanks to everyone, all your feedbacks are useful for me. Some of you say that I could talk with a psychologist first, and then to my parents...I've always thought to do the contrary, but maybe this could be a good idea...but I'm not sure yet. I don't know if there is this service in my university...maybe I could find a psychologist elsewhere, but I don't know how. And I'm also worried that my parents remain badly because I didn't want to talk to them.
But I'll think about this. However, I can think about it, but to really do it...I'm scared

Maybe I shouldn't, but I am
