I'm not even on T yet and in the last 3 years my frustration levels have gone through the roof. I have punched doors and trashed rooms, which is uncharacteristic of me. But I do put it down the the ramping up of stress at home to almost unbearable levels; coming out didn't help, but many other problems like family acting like jerks, money stress, and a very small living space shared with someone else who is abysmal at being social and doesn't recognize when they are being an ->-bleeped-<-. And I can't leave this situation at the moment.
I noticed in the past when I became angry I would simply feel kind of upset; now when I feel it I can literally feel a sensation that flashes through me and an impulse to be violent toward something. I say something - objects. There's still a very strong check on me ever hitting a person, which I won't do unless they do it to me first. My mother is a violent alcoholic and I'd lose all respect for myself if I ever became like her and started using other people as punching bags.
It is best to find ways of avoiding becoming angry in the first place. Being angry puts physiological stress on the body, but causes much longer-lasting problems in your relationships with other people. I've stopped interacting with others in a way that I know leads to arguments and issues, and I do just shrug and walk away if I see it going that way. The other person I live with has finally started to do it as well, so it works twofold now. Just ask yourself is it something even worth getting riled up about, especially if it's just some disagreement or someone being a jerk you can walk away from. If you do still become angry, it might be an idea to get one of those stress toys or hand exercisers. Just the practice of focusing on an object and grasping it can take your mind off the issue and stop you hitting the roof. I think - it's just my opinion though - that those with more masculine minds and personalities or those on T probably get this kind of reaction because action - doing something about a thing that is a problem - is a very 'male response'. If it's not a constructive action, the urge to just "do something" about your pent up feelings can just as easily become a destructive action. So try to make it something constructive. Leave the room, talk a walk, go distract yourself with something you enjoy like a movie or game. Anything but sit there boiling over, huh.
I get the feeling over time I've matured into a male and my mind has become increasing more male-like... as when I was younger I'd be happy to just sit and stew about something, and was never that angry about it... but now I know there are problems if I sit and stew, and that getting angry gives me headaches which can't be good for blood pressure, and that a lot of what gets me angry has some long-term context in my relationships to other people. I've identified what it is that gets me angry the most and it's this - people being hypocrites or outright disrespectful, within the context of our specific relationship. So my advice would be to pinpoint what it is that sets off your anger particularly, and take steps to avoid it. I've avoided those people who infuriate me for the most part, and I haven't felt angry in many weeks.
