Bipolar Depression

I am currently experiencing a massive amount of hatred toward my boyfriend and I'm having trouble calming down and thought getting it off my chest might help or maybe I could get some advice. I told him when I got home from work I told him I don't think my new generic med is working properly. So I went to rest quietly and try to rest. While I was trying to rest he started an argument with my 9 year old that made him cry and have a melt down. On a side note my son is in therapy working on many different skills. So anyway I think he was in the wrong and sent my son to my mothers house because I didn't want him in this tense situation. So now basically I'm so angry I am thinking of leaving the relationship for my son's well being and I no desire to forgive my bf for being so mean
