i feel the same thing at night, usually though when im starting to fall asleep or just starting to wake up i have the sensation that i cant breathe especially when i sleep on my left side or my back, when i get up in the morning i am so freaked out by the sensation that i feel like im going to faint! its a horrible sensation at first i thought it had gone away but last night it did it again! i feel like im going nuts all the time! The doctors have looked at my throat and ears and said there is nothing physically wrong with me, i hate it :(
Well cj29 couldn't have said it better! I agree 110%! Night time is the worst for most people who suffer from anxiety....our minds travel more because we just laying there with nothing to occupy our minds with. I would certainly see a doctor and talk to them...they are not going to think you are crazy! Your fears will be put at rest! Wishing you the best of luck and keep us informed.
Some of my worst bouts with anxiety used to come at night when there are less distractions to occupy the mind with. Panic can set in at any time; have you gotten this checked out by your doc?
