<human>: So i have been struggling with depression over the last year and recently its really starting to get to me. My GF of a bit over a year and i had dated when we first went to college and i broke her heart then so its always made things a little complicated, that was only because i was young and an idiot.

My GF is perfect but being in a relationship is really making it harder on me as i feel responsible for her happiness too. I almost went home from work the other day just because i couldn't deal with the idea of any of it. She isnt pushy at all and is really supportive and so i feel even worse about myself when i think about breaking up with her.

Summarize the given text in a few sentences.
<bot>: Im depressed, im thinking of breaking up with my supportive GF of a year (whom i previously dated and broke up with) because im struggling to deal with everything.
