Terrified!

Na
I went to sleep. And i am normally sleep on my back due to me still healing from a major surgery that was done 11 weeks ago for myasthenia gravis. I have still a little bite of pulling of my muscles and a little soreness from the surgery nothing major.I jumped out of my sleep due to me not being able to breath and also had an anxiety attack. Had we trying to the rest room because i had to poop(sorry). My anxiety has stopped my head feels light a little. Im just terrified about going back to sleep.
