My day went from great to pretty shit lmaooo

I almost had to kill my dog tonight. It was a necessary measure because it had gotten to a point where it was either me or him. It all started first when he had attacked my little brother. He had bit him on his hand. I went up stairs to get him and that's when the showdown ensued. Before the scramble I could see the fright in his eye because of the anger in my voice as I ordered for him to come to me. He started to growl and he attacked me. I immediately defended myself, unfortunately he got me pretty good on both my hands and a slight punctured wound on my hand. When I finally gotten hold of him I was not letting go, I was going to crush his windpipe with the hands that god has given me. Even now minutes after the scuffle I am still "Seeing Red". It has been a while since such a corse of anger has erupted inside of me and I am definitely not very find of such an emotion because I know no bounds to which extreme action I may take. After it all I kind of view the event as a sign, a sign that says be careful not to corner. Even if not intentional do not corner. I just hope what my mind is thinking right now is just the adrenaline creating an hysteric imagination and not my actual mind thinking these thoughts right now. I just need to breath.
