I came to the point where i thought why should i have to explain myself to anybody?
Amen! And you know what? You don't. Especially not to her, not about anything on stupid Facebook. She has better things to be worried about, and you have better things to do with your time than deal with all that!
I like that you went for a swim. Did it make you feel better? Glad to hear you value your sobriety. I can certainly relate to being worried about what others think and trying to get all that out of your head. Keep the focus where it belongs - on you and keeping yourself well. You're doing great.
