Anger Problems????????????????

My family is terribly annoying especially my sisters(and theirs 4 of them) when they beg they usually get what they want from my parents and try to use it on me but when they continual beg me and beg me over stupid thing i become very angry and walk away usually giving them what they want but after i walk away i kinda get this burning feeling inside like i want take my anger out on something(violently not like stab something violent but like hit something) and there is many times where i was tempted to punch a whole in my wall over my family annoying me but i would get in trouble and would have to fix my wall >.>. I have to keep my anger pent up inside all the time and try not to be violent towards anyone but it gets harder every time I become angry so should i try to relieve this built up anger i have gained over time from many things and if so how?
