Way to go, Milly! I'm rooting for you, and, might I add, very proud of your decision. It might seem like such a simple gesture to make a decision like that, but believe it or not, it can mean the difference between a life of misery and the start on the journey to recovery.
(and don't forget, any little slip-ups along the way, are only that - don't let any temporary setbacks set you back permanently ).
Wishing you a happy journey!
