I'm just letting out how I'm feeling right now. If there's an issue let me know, please.

I feel very furious at my brother sometimes. I just feel annoyed at him. He's usually nice but sometimes he's a jerk. I know that happens to everyone but he can get rather mean. When he gets mad, he likes to insult me because of how I look, what I eat etc. He apologizes but not before I almost yell. Then afterwards I feel mad at myself for starting something (which I sometimes do). I feel bitter and feel like I hate my brother. I feel awful for having these feelings because I don't want to hate him and he honestly isn't a bad guy but when he makes me mad I genuinely dislike him.
