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?
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.
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 :(
