Monday depression

What ever has happened I just keep telling myself it's not the end of the world. I can recover; I can get up and put a brave smile on my face. I hope I don't come out of this with a heart made out of stone. But why would I want to have a heart, you only get hurt. Love again? No, thanks. Why do we go and do the same mistakes again and again. I'll allow myself sometime to be sad, just to feel sorry for myself. I know it's a waste of time, but that's my way of recovery. Another thing to remember, you are better off alone then with the wrong person. So what's so positive about this Monday? What ever has happened it’s not the end of the world. Time heals.
