Burst at Brother

Yesterday, I was having a rough day. From about 7 in the morning until about 7 at night, I was running around and did not even have a minute to lie down in my bed in relax. I went to school, then I hate to tutor, I went to work, I went to the supermarket with my mom, and then I worked out on the treadmill. I was very exhausted at the end of all this. When I get tired, I am one of those people that tends to get cranky. It DEFINITELY was a cranky day yesterday. I was sitting at my kitchen table and my brother was just asking me these random questions. I didn't really have the patience at the time, because in that moment I was looking for alone time, which he was interrupting. He kept on talking to me and I just couldn't help myself. I yelled at him. I think I said something like "Get out of my face! You are soooo annoying! Just the sight of your face and noise of your voice is really bothering me!" What I found after this anger burst was that I felt my guilt and immediately knew that I did something that was completely out of line. I find that I am beginning to realize when I should get angry and when I should avoid the situation all together, or refrain myself from yelling. I needed a couple of minutes to cool down. I learned that I shouldn't face someone I am upset with immediately because it could lead to another anger outburst. I cooled down, listened to music for a little bit and apologized to my brother. I actually felt really GOOD after I apologized to him.
