I don't check in here very often, but just read the smoking poll/thread and do find it very interesting the number of people with HA that smoke.
I suffer from HA all the time, but it's mild and fairly controllable. Just knowing that I have anxiety (as opposed to something terminal) does help most of the time!
I'm 37, and male, smoke about 10 a day and give up regularly only to crumble and resume as soon as things in life get a little tricky. I even fear that I start smoking to fuel my HA as stupid as that seems.
Every year or so I go into complete uncontrollable meltdown with the fear of lung cancer. I get chest pain, back pain, sore throats, hoarseness, small amounts of blood in my sputum etc. I have all these symptoms now and had to leave the dinner table tonight halfway through the family meal because of the fear.
My biggest fear is of telling my young children that I'm going to die. They're too young to understand.
I can't work out why it happens only once a year with this severity, although obviously all year round too, but controllable.
