Tabitha actually had similar problems with some of her former friends. She had grown up on the streets most of the time, due to her desire to hide from her parents. So, she had learned a very different way of having fun from the other kids at the institute. This had led to her clashing with Professor X more than once. And then there was Mystique; she hadn't been too fond of the moment with Tabitha had blown up her room, because...well she felt like it. So, her friends tended to be people that at least understood why she was the way that she was.
