My friend is really rude to me???? Help please?

That's like with me but not a guy friend and not names like that. My friends just insult me-jokingly-or make fun of me, but even if you know they're kidding it can still hurt. Look at his face when he does it to make sure that he's joking and if you can see that his face holds even a slight bit of seriousness when saying it than maybe he isn't a very good friend. But if it really bothers you than talk to him if he truly cares about the friendship than he'll be better. I know how it feels like to have low self-confidence and having friends that just in some ways shoot it down even more. But talk to him, it couldn't hurt anymore than those names. And if he continues than he isn't worth the hurt.
