Anger management...........?

every now and then whenever people tell me i'm wrong i get this little fire started in me. its sort of like having erflies in your stomach, but replace those erflies with angry wasps. even when people make comments like "oh you're not suppose to do it like that" i get so angry and i want to just yell "I KNOW GOD DAMMIT!!! SHUT THE ***** UP!!!!!" but i try my best to contain that (usually i just say "i know >:( i'm not done yet...). whenever my parents open the door to my room to get something i get so angry and give out a huge sigh (my parents get angry at that....) and when they dont close the door after they leave i just want to grab the door and scream "SHUT THE ****** DOOR!!!!!" i just feel like cursing all the time. whenever my sister (baby sister) runs around the house when i'm about to sleep i kick the wall to keep myself from screaming. without me constantly listening to my music i would have probably wreck this whole house. but i cant listen to music all day. i have school to attend to. and there many people make retarded comments that make me want to scream. i feel like i might snapp at someone and they'll take it the wrong way. after that i'd be moody again and so many problems would errupts just because of that. i wish i could stop being so angry all the time just because of such small things.... i want to stop this but i dont want to take anger management cles. are there pills for this??? or any alternative of decreasing my anger?
