You need to get out of yourself. Nobody does you worse than you. Nobody torments you more than you. Nobody makes you feel worse than you. There are times when you need to get away from yourself. Sometimes you have to drop everything and leave. And that is when you let go. Because running takes you nowhere.
If you are trying to change a; person, relationship, or environment, and it doesn't change - leave before it changes you. Things are what they are; you have no control of that. You are what you will; you have full control of that.
