sleep brings it back?

i have ended the past two days in better spirits but it seems like when i fall asleep i wake up having negative thoughts like i am getting worse and the what ifs ALWAYS come rushing back. it takes me almost all day to get my bearing back. i sweat, i tingle in my hands and feet and around my mouth , i get super hot all over and sick at my stomach to where i always end up in the bathroom. i know that the physical symptoms are just panic attacks but i seem to lose my will during sleep. yesterday i had just come to the conclusion the heck with it bring it on and i actually got to feeling better but through the night the reallity hit or the what if's as i call them it did come what then. IT WOULD BE BAD i know and i fear it. any thoughts? does any one else do this?
