Anger Management Help

So I know that some women who use glow are doctors and nurses. My boyfriend (21) had payed football all of his life. He had suffered many concussions of which he was never seen by a doctor for. He is waiting on insurance to kick in, and it should be very soon but I don't care about cost at this point because he needs help. He is very very angry everyday. He is on the verge of losing his 2 month old daughter and myself. Is a neurologist the way to go for this? I think that the drugs would help since they tend to level people out. I've only heard success stories. Please help if you can.
