Hi there! Congratulations on being proactive in your self-development. I don't have anger isues but my problem has always been that I'm too emotional in general. I would recommend trying a few types of yoga but also..just remember that it doesn't work they way you might except it to work. It changes you from the inside slowly.
I expected to feel calm and zen during class. In fact, my mind would get more active and even more aggresive than normal in the beginning of the session (I do ashtanga yoga), then about halfway, it's like all that fire inside my head is burning out. By the time I'm in the closing sequence I feel like I fought and won a battle inside myself and what I believed possible of my body. I fought the urge to quit because I wasn't "good at yoga" or "not showing enough progress". My mind is quiet.
With kundalini yoga, it's a different experience...I feel stupid and skeptical of this chanting stuff (like, every time) but then something happens and suddenly I feel light and happy. But that only started to happen after I tried it for the fourth time.
So, give your class a month or so, and if you feel it's not for you, try a different teacher, and then try a different type of yoga (there are so many styles now!).
I also do "micro-meditations" during the day (5 minutes during breaks instead of facebook) and this helps me get some space from my emotions. There are lots of apps to make this easy for beginners if you search. I have a long way to go but it's fair to say i'm no longer ruled by reacting to things all day long like before. Lots of love and support to you. xxx
