Anxiety and health?

I have bad anxiety which causes me to worry about my health all day. It was my stomach before now its my head. It bad in the moring I feel off balance and sometimes have headaches but not to bad. I can walk a stright line and stand with my eyes closed ok, but when iam walkin i fell off balance and i panic. Can anxiety do this if iam constanly worring. Also will have have some mentall confusion too. Mom says it all me but i dunno. It seems it got worse after i was sick a few weeks ago with a flue. Iam worring about tumors. I never fallin but i dont no if its all anxiety and stress. Iam a 20 year old male thanx
