I CAN'T DEAL means that you don't have the mental or emotional capacity to handle something (at a given time because of other factors, problems, worries, etc) - you're about to lose your mind. A better translation would be ...для меня чересчур, слишком много для меня, or something along those lines.

А-а... Я не вынесу твоих обвинений?

Maybe. The meaning is like “this is too much for me to handle right now”

Выше моих сил терпеть то, в чем ты меня обвиняешь (?)

That sounds more like it))
