I haven't been able to sleep in ages at night. I lied down in bed yesterday at 1 am and woke with a rapid heart beat and a terrible panic attack at 3 am. So today I had to wake up early with only 7 hours of fitful sleep. I was feeling gassy all day and I had pizza. I didn't feel it satisfy my hunger and then I was so nauseous I vomited and passed watery stools. I went to my GP he said I had food poisoning. And now I feel palpitations and shaky feelings. And I feel so sleepy but I am so scared of waking up to a racing heart and a heavy body. Once I have a panic attack my body gets so so heavy I can't tell. It's hard to move my feet. Please help.
