I bought Fake uggs, help?!?

Ok so my mom bought me new uggs from this discount website, but apparently they were totally fake. She didn't know they were fake until after she got them and she told me that she didn't feel like going through the trouble of sending them back. I'm afraid to wear them at school because they look EXTREMELY fake, the seude isn't even real suede, and the soles are wayyy to skinny to be real uggs. Do you think people might notice? I'm afraid they might laugh at me if they find out my uggs are fake. And trust me when I tell you they look fake! It's super noticable. (there is a tag on the back of them saying ugg)
