It’s starting to become very hard for me to deal with my girlfriend and her emotions . It’s becoming hard to differentiate between Her “Real” feelings or her Anxiety /Depression .

I want to be here and I want to be able to understand her and her feelings so that way I can comfort her and fix something if need be but my confusion comes when she will talk or send me a paragraph that summarizes to her hating me and wanting to leave me etc and it seems to only happen when she is upset but when she isn’t upset and I ask her about it , she explains that it’s her mental issues. And then she’ll take that back as well next time I make her upset .

Please help I need to know what I need to do
