I Had A Pimple And I Used Tea Tree Oil

I had a pimple and I used tea tree oil to fix it. It didn't work and became a scar. A BAD scar. So then I kinda peeled it off, I thought it would work. Then my skin was off, between my eyebrows :( I then put some acne cream on their and slept. In the morning it was even worse. It basically is peeled skin. I don't want to go to school like this..AT ALL. How long will it take for the skin to grow back?
