I found out my girlfriend has depression and now I plan on breaking up with her.
Why would that make you want to break up with her?
Because she's crazy and I cannot cope with it anymore.
It can be difficult to deal with somebody who is going through things but it is not good to judge them and break up with somebody because of it. It would be better to learn more about it and work through the relationship.
Yeah, it's probably for the best that I break up with her.
I think you should really consider your actions that you're about to take. It's important to be there for people that are dealing with depression. Breaking up with her could cause her more harm.
