I fucking hate being "too white"

Everyone doesn't like me, not specifically because of my race but I'm just sick of hearing people say "you can't say the word" or "you're too white" today a girl straight up told me that I'm not really black because my mother is white. AND SHE WAS FUCKING MIXED TOO! I'm going insane with the fact that so many people don't count the fact that I'm mixed, and I've even been mistaken for Hispanic.
