Today, I hurt myself

Maybe it was me, I was jealous or I hate to see he lost hope in me. I just wanna take revenge. I want to pay him. Just wanna show that he is not the one who is in my life. I went for a jog this afternoon, and I force myself to run 4 more rounds as I had ran 6 and 1/2. I know its funny to see, but I just started my exercise recently, so my stamina is quite weak and not that good. I hurt my waist and my muscles. Its pain but when I think of something I wouldn't want to think of, I will run.
