Yep, that totally happened to me too. For me, it started within a few months on T, and then it ended by 6 months on T. I think the change in my hormone levels caused it, and then once my hormones leveled out, I cooled down. So it could be the same for it, give it a few more months and it could go away.
I never had that big of an issues dealing with it, that is I never hit anyone. I know how to walk away when I'm pissed off. but I still just didn't like feeling that way.
My doctor told me to keep a calendar of when I get my shots and when I feel more irritable, in case there's a correlation. And for me there was, my doctor told me to lower my dose, which made things worse, so then I upped my dose, and either that helped, or by then it just went away on its own.
