Opinions that do not matter

I have to remind myself sometimes. It's not easy, because before yours was the only opinion that mattered. Now, what you think about me has nothing to do with me. 

If you don't want to believe me, I do not need you to. Your mood is not my responsibility. I don't have to fix it, make you happy, explain myself. I did what I did and said what I said. How you take it is entirely up to you and has no effect on my life.

I know what it said is true, and my opinion of myself is what matters.
