I know how you feel, last night I thought I was going to explode at my bf and only just stopped myself, I thought I was going to cut, instead I just sat there and thought, I ended up crying and pouring my heart out to my bf and felt better, better than if i'd gotten angry or cut.
I guess what I'm saying is anger and cutting almost got in the way of me dealing with emotions I needed to deal with.
I felt horrible inside and my response was anger and an urge to cut which would have gotten me no where, I have no idea how I got past them but I did and it really helped.
Maybe the cutting isn't helping because the issues are still there and the temorary relief of cutting just isn't working anymore so now you end up angry, if you are able to control your anger then you may very well cry and vent, that might just be good for you.

thats the problem i cant it part of my learning difficultys i have stress anger n emotional issuses and when i do break stuff n hurt people i dnt no i doing it

Then I guess what i suggested will be harder for you to do but still give it a try, if you feel even an ounce of anger try to get to what's behind it, I know it sounds hard especially in your case but worth a shot right?

i get angy wen people dont understand me and coz they dont understand me it makes me angry n coz it makes me angry i break fings n then i cut myself coz i feel sad coz i broke sumfing or hurt sum1 n then i break or hurt sum1 coz the cutting doesn't do it 4 me

Sounds like a vicious cycle, are you getting help for how angry you are feeling?

i cnt got to a counciler coz if they dont understand me i would get angry i cnt play rugby coz of ma knee n shin n i cnt box coz the last time i did i hospitalized my oponent 4 3 months :(

Tell you what, try telling me about you, write down who you think you are and why people don't understand you, maybe if you understand why they don't understand you it might make it easier.

i tryed that with ma former counciler it didn't go very well i just destroyed the room n ended up gettin aressted

Well since I'm at a safe distance I'm willing to try if you are and ONLY if you think it won't cause you any harm.

thanks 4 the offer bbe but i dnt wanna cut myself like last time i drew pics all over my chest n belly in pen then cut them with a knife

It really sucks that you can't seem to deal with your anger, there must be people out there who can help, tell someone close like a family member and ask them to find out for you maybe?

u cud do sumfing 4 me just b a friends thats all i really neeeeed is a friend 2 care

I would be happy to do that :)

yay i have a friend :)i calmed down a bit already

I can understand where your coming from its like the anger you have keeps adding and adding and you just want to let it out on someone so they can be hurting too. If you try maybe talking to someone close a best friend maybe it could help it always helps me to just write down whats on my mind then throw it away so nobody else reads it but then i feel like i have let out my feelings without including others.
