Hi - yep I can relate to all you ahve said. Mine started when I wasw 12 my granparents were both very ill and died and I became worried it would be me next. I then got like a stiff jaw and sore stomach - all classic stress/tension symptoms - of course to a 12 year old I though.........lock jaw, appendicitis etc etc. As I grew up I went through phases of being concerned with my health - if all is huncky dorey it is really not a problem - but if stressful situations arise or things that make me feel not in control - the physical symptoms appear - for example tight chest, shortness of breath, rapid heart, headaches, spaced out feeling etc etc - the list is so long I would run out of space. I really though that it was all due to real serious and life theraetning illnesses and the usual cycle strats up - feeling weird or ill - worry - thinking oh cancer etc - trip to the doctor - reassurance - subsiudence of symptoms. I am now 30 years old and it has taken me until probably 4 years ago to realise that most of the worry is just that worry and fear. Most of it is thought based - oh god it is serious I ma going to die, what if I have cancer, what if I have heart failure etc etc. I got some counselling - very worth while - actually it was counselling iin stress management that dealt with how to tackle these health fears. I am loads better now - and I now can recognise when a symptom is anxiety driven and when it is real. Basically if you are anxious type person (lots of us are) you brain has a wonderful tactic of jumping to the worse case secenario. Alot of getting in control is kinda tackling the thoughts of - oh god what if.... with thoughts of - well i have never been srerioulsy ill before why should I be this time. Also accepting when the doc tells you it is all OK - that you reallya re OK. For me it deffinately helped having a GP who I felt very comfortable with and that I could speak openly with. Of course over the years I have had some real illnesses which were nothing to do with stress or anxiety and reallly did require treatment. So I ,ma not saying do not visit the doctor. You need to try to relax, practice deep braething, burn the home medical books andinterneyt searches - i have so been there and done that i know. Loads of people have these knida problems it is just a matter of learning to cope with them. Incidenatlly I have never been told that I am a hypocondriac what I have been told that is that I suffer from sycosphymatic symptoms - plain english - stress/worry etc manifests itself in physical symptoms that in turn cause mental worry. Good Luck!!!!!!!!!!
