I have had this exact experience a few times- for me it was anxiety. Basically I was drifting off to sleep and the next thing I knew I was jumping out of bed, GASPING for breath, unable to breathe. Scary stuff.

I'm sorry this is happening to you. I think seeing your doctor is a good idea. If it's a medical issue, you can get help, and if it's anxiety, that will help you know what direction to go to help yourself feel better.
