Health Anxiety...normal or should I be worried

[chels]

Hi, this is only my second post ever so bare with me... but I have terrible health anxiety with a bad fear of dying. a week ago I knocked my head decently hard and I worried this whole week over having a concussion or a brain aneurysm, panick attacks 3 times this week over it all! I finally started calming down from that specific idea but I still feel really anxious. I never know if the way I feel is just symptoms of my anxiety or real cause for concern. my stomach is pretty upset all the time and my head feels really, really weird.. I don't really know how to explain it other than my head feels heavy but I'm lightheaded at the same time... if that makes sense? I just don't know if any one deals with the same things I do, and it would be dealt reassuring if I knew someone did..
