How to remove fake tan??

Be

I’m an incredibly pale person and because I’m in a show in two weeks I wanted a slight tan to look a bit more human with the lights.

To put a long story short I’m now covered In random huge spots of orange!!!! It looks horrendous I’ve spent all the day exfoliating, using soap, and baby oil to attempt to get it off! I can’t use a tan remover because when I went the shop to get one the woman told me it would make it worse because the brand I use don’t do one so the chemicals wouldn’t work or whatever.

HELP ME I cant leave the house without being stared at! And it’s too hot to be in clothes that’d cover my whole body😰
