I think I'm going to break up with my girlfriend because of my mental health problems.
Why do you want to break up with her over that?
I just do not really see any other option here.
I understand, but it's mean to take out your issues on a loved one. You should try to see it from her view.
You don't understand. Mind your own business.
I'm only trying to help, and I'm sure that your girlfriend will try to help you too if she understood. It's not fair to break up with her without explaining why.
