While I cannot give you a truly solid answer, as I do not know you anywhere near enough for such (and this kind of subjective analysis is already flawed enough in the hands of a skilled professional, even more so in mine), I do have a suggestion: strive to second guess yourself, no matter how much you may feel wronged by the situation. I tell you this not so that you may try and immediately prove yourself wrong in the source of your anger, nor that you may review its consequences in the heat of the moment, for both are highly unlikely.
Appealing to the logical irrelevance or soundness of said anger are merely two of many means of coping with an ultimately irrational feeling, one that may derive radically different reactions from individual to individual and wholly taints one's subjective rationality. What this suggestion does, however, offer you, is a chance to interrupt the cycle of self-pity and rage that often ensue and scale into the outburst you speak of. If you are giving in to physical violence, or suffer emotional outbursts to the point of crying, odds are you've overblown the situation.
While that may not be the case at times, and those times do exist, it is only once you've accustomed yourself to doubting your impulses that you may actually conceive of, not mastering them, for that will never truly happen, but rather, withholding them. Ultimately, one stands to lose more emotionally by giving into the impulse than by delaying it, so one may re-approach the topic more reasonably at a later date. Try and rein in the righteousness of your anger, lest you come in the wrong.
That said, do excuse me for any undue assumptions I may have made.
