Is OTHER wrong in the post ? POST : I've been dating this girl for 5 months, and last month, we decided to to make it official. However, she only revealed to me that she has depression last week.

One thing you have to know about me is that I'm a 22-year-old guy who can't handle negative emotions very well. She knew about this even before we started dating, because I was known as the quiet, carefree guy with a dry humor. Whenever there's drama, I'm usually ten feet away from it. She also knows I have A LOT on my plate (health, personal, financial issues), but we pushed through with the relationship believing it would be good for us.

I've also previously dated a girl with depression about 2 years ago. It ended with her almost slashing her wrist in front of me (I don't know if it was a guilt trip tactic or if it was real, but I didn't want to find out), so I pretty much avoided girls with mental illness since then.

When my new gf told me she also has depression and is also suicidal, I was speechless for about two minutes because I was really shocked. She seemed pretty chill and fun when we were hanging out, although there were times she was really down (I chalked it up to work stress), which I thought was pretty normal for people our age. I then told her I could not go through with the relationship and explained why. I tried my best to speak calmly and in the nicest possible way. I was also careful with my words, in the hopes of not triggering her. She was also pretty calm during the conversation, although I could tell she was holding back her tears. Her best friend also called me up to ask if we could give it another chance, but I told her I need time to think 

I really thought at the time that I had no choice but to break up with her because I couldn't give her the emotional and physical support that a person with depression demands. However, I'm now having second thoughts because she might do something harmful to herself or others as a result of the breakup, and I care enough to not want anything bad to happen to her.

So, AITA for breaking up with my girlfriend after finding out she has depression given my circumstances?
