Okay, so this is going to sound kind of stupid. Recently, I did something really stupid and I got angry at myself and I banged my head against the wall a few times kinda hard on purpose. It didn't really hurt that badly, but then I started thinking about what happened with the actress Natasha Richardson, who hit her head skiing, showed no symptoms of a concussion, and then suffered a fatal brain aneurysm literally hours later directly caused by the blow to the head.
Right now, I'm scared and I dont know if I should go to the hospital or not,
