Hi Kelly,
I am a miagraine sufferer and I have Panic Disorder (for about 4 years now). I am going through the same thing as you at present and I also worry about dying in my sleep or when I am alone... it is much worse today than usual.
We tend to focus on things when our panic is at its worst, it can take up all of your time. I find I don't want to do anything as I would rather sit on the couch and think about my symptoms.
Today I have tired, unfocused eyesight, I have very heavy legs and I have a headache which has been going on now for three days. I cannot take anything for the pain as I worry I may have a reaction to it. My neck is very tense & sore (probably from not relaxing), I'm dizzy and I am worried I may be in line for a stroke and/or worse.
I too have had all the checks and believe me 98% is very normal! No doctor will say you are 100% in case something out of the ordinary happens and they become liable.
I am concerned too, I shake, I feel tingly - it feels so awful and you feel like nobody understands how urgent the matter is... but you are going to be fine. It is horrible and it is very scarey but it will pass. I have had these feelings now (gone to ER's and doctors) for years and only recently am I accepting that it is panic and anxiety and that there is not a lot I can do about it, no matter how many times I get checked for blood clotting or similar I worry about the fact the doctor may have missed something & I should go back tomorrow if I still feel the same.
I am not dying, I constantly think about it, but in reality how many millions of people are walking around every day & don't give it a second thought? We are sensitive, our symptoms are 10 times worse than the average person with a miagraine, headache etc.
I hope it gets better for you, this site is wonderful for venting and getting advice - use it often. I hope you get some rest tonight and enjoy tomorrow that much more.
Toni
