I have *sort of* a similar issue (I'm almost 17 as well, btw) ... I get scared of panic attacks whenever I know I have to go into a hospital or doctors office or anywhere where there are sick people, because I have an extreme phobia of illness, esp. people vomiting in front of/around me.
It really sucks ...
If you ever feel like talking, just send me a PM and we can chat over MSN if you want.
*crosses out "of" and replaces it with "and have"* XD
