Anger is a terrible emotion, and so hard to deal with but sometimes i feel my anger comes from a panic of being rejected, or some1 leaving me.... i could have the simpilest arguement with my boyfriend and the first sight of him even leaving the room to cool down drives me crazy and i flip out, ive always had a close bond with my mum, but always found it so hard to trust other people, and when i do begin to trust them and they try to leave me or walk away i cant handle it and freak out and end up loosin them anyways, and i was never like that as a child, not until my late teens/early adult hood!! I dont think ur an angry person in general, ur anger comes from somewer, and i think its ur insecuritys a bit like myself!! i wish i had some advice for you but all i can say is try to stay strong, keep talking and get help
