Im in a toxic freindship.

Im in a toxic freindship. He Just seems to find a way to bully me. He always makes innapropiate jokes, bully me because im "weak", makes fun of my parents. Sometimes rarely he acts good but then i get comfortable, then he uses me like im his slave, i give him half of my lunch and he says "work for me you wild pig" yes, he says that. And i feel like i depend on him and Just cant make a big move. I need to break up with him but i feel like i'd be aline and lonely without him.
