Oh dear. Silly girl. I do not understand why people think they will be fine with no cream on!! /rant
Right, run a bath and put some t-tree oil in there. Drink lots and also take some ibuprofen. Get some aloe vera gel from the chemist or Superdrug and lather yourself in it. Morning and night for a week until you notice fine peeling. You'll probably peel a couple of times if you are at the blister stage. Once youv'e started to do the fine peeling (i mean flaky like scurf) then you can start to use a gentle wash cloth to rub the flaky bits off in the shower. Then more aloe, or if you prefer cocoa butter. You should be ok, but do be more careful!!
