I feel for you and can relate. These are all symptoms of your injury. I had some teribble mood swings at first and got put on the lowest dose of depacote. It helped but did not eliminate them.

I had to figure out my anger was mostely tied to my frustration in trying to do and cope the same way I did before my injury. Try to be aware of your frustration level and realize you must stop or redirect your efforts until it goes down.

I found learning about concussions helped alot. Hope you feel better soon.
