It's a bit late now but for future reference, you're supposed to bleach your roots last to avoid them lightening more than the rest of your hair. You say you've tried everything to fix it, what exactly have you tried? The best option is probably to wait a week and bleach it again as long as your hair doesn't seem too damaged (get a professional opinion on this if you aren't sure). If not, it might still work. I used colour remover to get rid of permanent dark brown hair dye and ended up light ginger ends. I then dyed it purple and it turned out fine. Obviously if you want it to look it's best and avoid risking it looking bad/damaging your hair go see a professional hairdresser.
