My younger brother is driving me to the point of insanity. What do I do?

this is a tough situation. it's hard to really confront someone who's hurting your feelings. you could try talking to your brother, explain how what he says hurts and you'd appreciate it if he stopped. if this doesn't work, you might want to consider talking to your parents about it. i have an older brother who used to be a real jerk to me, we'd get into some nasty fights and he'd say absolutely HORRIBLE things to me. but as time went on, we both grew up and now we rarely fight. sometimes the best thing to do is wait it out.
