Open wound on my arm...Keeps giving off liquid..What do i do?

I tried this home remedy on my arm and a literally circular portion of my skin bubbled up in just a couple of hours. It had liquid under it. I took a shower and "popped" the bubble circle only to leave loose hanging skin...So i peeled the skin off. Now im missing a couple layers of skin, so much so to a point where my arm hair follicles are very distinct. Bandaids are too small for the spot so I put guaze and tape. And within minutes the guaze is a yellowish color and the liquid is seeping through the tape..if i push down on the guaze, liquid comes out...What is this? What do I do? Hows it gonna look when i wake up? lol I put baby powder on it after the shower to "dry it out" and now there is like white gunk on that part of a skin and i tried removing it with a q-tip but it stung so much so it put bacitracian and guaze and imma sleep on it like this and hopefully clean it in the shower tmrw. How long will it take for my skin to grow back???
