<human>: Can you succinctly summarize the text in 1-3 sentences?

My girlfriend is an amazing person. She started dating me when I was at my biggest of 350lbs. I am now down to 280lbs. Without her, I wouldn't be able to tackle the challenge of losing weights and my prior demons which caused me to eat so much. She brought me back from the throws of sadness that had pained me for years over school, family and life in general.

We all have our demons, and she has many. A dead father, a shitty ex-fiancée, an irresponsible mother and crippling debt from school. These things get to her… a lot. She totally has anger issues. The slightest thing will set her off on a course of anger that is unmatched by anything I have seen, followed by hours of tears.

Granted, I am responsible for setting it off. I am absent minded about simple things and often forget minute details about everything, and this drives her mad. It makes her feel insignificant and pathetic, but it seems to me a gross over reaction to everything, all the time. Lately I could not inform her of something a mere hour or two after I learned about it and it sets off this unbridled rage within her.

We have a lot of great moments together, we really do. I just don't know what to do with emotional instability. I don't know how to deal with it, where it comes from (despite my repeated attempts to probe the situation) and what to do going forward. I feel trapped at times; sick that this whole relationship is crumbling because of my inability to do anything "right" when she needs me to do it her way.

Any suggestions?  I really don't know what to do. Obviously, I will answer any further details if need be.
<bot>: GF gets upset at everything I do, and I don't know how to get her to calm down and enjoy the relationship despite her past experiences
