Thanks for the post. I had 3 of the 4 concussions less than 8 months apart. The final one was an assault and happened a few years later. My bipolar & borderline personality disorder definitely got worse after the last 2 traumas & I have been suicidal off & on for years as well. I had no idea about this website & found it by chance. I've been feeling pretty much alone & wondering if I was just imagining a connection between the concussions & my headaches now. I never suffered from migraines or headaches prior to my concussions. People don't realize how severe a concussion can be until they go through it. I have headaches every day now & I'm afraid it's only going to get worse.
