Hi Donna
You're certainly not on your own with those sorts of feelings. My head quite often feels really heavy at times and it is mostly at night more especially so if I'm overtired.
I also do still get anxiety attacks but not as bad as the one you had. I'm on my own most nights and when its really bad I have to read myself to sleep to take my mind off the feelings of panic.
Like Stephen I try to find other things to do too much concentration on any one thing has always made my head muzzy and sore.
