Your life is worth more than that.
You are worth much more than that.
Write those words down on a piece of paper. Write it down and read it when you are angry, frustrated, tired and numb, when you feel lost and alone with nowhere else to go. Write it as many times a day as you want. Write it often. Write it on a piece of paper and tape it to the bathroom mirror. Write it on another piece of paper and tape it to the fridge door. Write it down and read it every chance you get.
Yes, these are very simple words for a very complex issue, and I will explain further.
