Opi! A thought only lasts for seven minutes! One hour at a time is way easier to manage than one day at a time too!
Do you have a picture of yourself from a time when you weren't using that you really like? Get that picture out and put it somewhere where you can look at it all the time. Let it be the reminder of who you want to be again! I have mine!
I don't have to tell you with each passing day things get better! You've been there before!
