Share your PUPPS relief!! (please I'm BEGGING you)

Slowly dying from PUPPS. I'm 39 weeks and absolutely miserable. My ENTIRE body is covered. (Even my buttcrack has it!!!!) I look disgusting. I scratch so much I bleed. I feel like I'm dying!!!! Here's what I've tried so far ...
Aloe
Calamine lotion
Coconut oil & lotion & butter
Oatmeal paste
Oatmeal baths
Cortisone & cortizone 10
Cold washcloths 
Zyrtec 
Is anyone else suffering from this?? Or has anyone found some type of relief or even a cure? I am planning to try the grandpas pine soap & aveeno oatmeal bath, I just need to go buy them. I seriously just lay here and cry. This has made me reconsider ever becoming pregnant again.. I had no idea how bad it was until I got it!! PLEASE HELP!!!!
