My depression started after a series of serious head injuries, including a brain bleed, a couple contusions and a couple concussions. I don't know if they're related or not, but it seems awfully coincidental. I do have some issues with mild aggressiveness that I have to really watch at work and other social situations. I've read a lot about recurrent traumatic brain injuries and I'd be happy to talk to you further if you want. Just PM me.
