Hi everyone, Im new to the bored, first post

Ive never been diagnosed with Health Anxiety but I have had periods of depression and anxiety before.

I have a strange sensation when I breathe and have to clear my throat (which I believe is an anxiety symptom), I used to be a fairly heavy smoker 15 a day for about 17 years.
I had a similar feeling a few months ago and worked myself into a frenzy (Dr Google) went to the Dr's who took blood tests, an ECG and a chest x-ray and all came back clear.

For some reason I have started to feel them again, and again went to Dr Google , I initially had myself down for COPD, but then went the full gambit and started looking at the dreaded Lung C.
Now I'm convinced there is no way with my smoking past that I am not dying.
This is horrible, I feel like its taking over, its my first thought in the morning and any time I log online I end up searching for stuff.
Dont even feel like working or anything.

I have found this site so I hope you dont ming me posting my thoughts even for my own therapy?
