i hate this feeling

....i think of all the normal and logical emotions i really really hate anger the most..i dont know how to express or get over it or deal with it or anything..its just there rolling around in my head and i dont know what to say to make it go away or become bearable again..i just hate when something sets me off like this and then im stuck because of those the first thing i do is start yelling at myself for being so stupid and after that comes all the wonderful thoughts of cutting just to make it all go away..and it doesnt really solve anything and if im trying not to cut then im just stuck with the back and forth feeling in my head and feeling like im going to explode because ..ugh i dont know..what exactly am i supposed to say or do to make it better?
