I agree with KatEyes. Please get a sleep study done. I used to wake up at night with panic and anxiety. I also used to wake up very sweaty. I had a sleep study done which diagnosed me with sleep apnea. I was having apnea events at night which I was unaware of.
Has your doctor suggested a sleep study to see if there's something going on when you sleep causing these episodes? For instance, sleep apnea floods the body with stress hormones and sometimes looks like anxiety. Don't know what all is going on with you, just thinking it's a good idea to proof positive rule out sleep disorders.
