Waking up gasping for air with panic disorder

This sounds like Sleep Apnea. I would recommend thinking about having a Sleep Study done, if possible. Especially if you are often tired during the day, have snoring, or relatives have it. I have Panic Disorder & Obstructive Sleep Apnea. Waking up gasping for breath is a very significant sign of Sleep Apnea. That was one of the key signs that I had before testing was done. I have been awoken by nocturnal panic attacks and I also wake up gasping due to sleep apnea - for me personally those two things feel very different.
