Yeah, me too. I didn't read the original books, but I looked her up on wiki after watching that new Alice one, and it seems people have always confused them since the creation of the character, and Tim Burton tried especially hard in that new movie to sort the two out, and make it clear that they were different people.
Just try to rest up on your little hiatus, lol. It sounds like you're overworking yourself, and that's not good. I mean, I couldn't imagine drawing one fanart for someone let alone, a bunch... Besides, it's best for us requesters to be patient and respect the artists' rights. Lol.
