i agree with lulu. maybe if you had the opportunity to speak to someone & really talk it through, they may be able to give you some strategies for dealing with the anger when it's building up rather than giving you something that means it never happens in the first place.

also, i don't know if you've ever tried yoga, but doing yoga is one of the only ways i can 'turn off my brain'. i have a terrible habit of thinking too much & my brain is usually going a million miles an hour. yoga is pretty much the only thing i've tried that totally chills me out & helps me to refocus. not sure if it would help, but i wouldn't think it could hurt

i reckon you've done the toughest thing - you've admitted it's a problem for you & that you'd like to change. it's not an easy thing to do but you're on your way now. i hope the doctor is helpful
