No i don't think you need to be fake. I think true friends will accept you the way u r. And if they can't then maybe there not worth it. Maybe you should find other people to talk to. Maybe someone that you would think that you couldnt mix well with, could be that friend your looking for. Keep your mind open, maybe you just need something new in your life instead of theses so called friends dragging you down.

Best of luck to ya :-)
