Thanks to everyone for the support and encouragement.
I feel fantastic today and back to my old self. The positive self talk is working and I know whatever I want to achieve is possible - even the snow is not bothering me! It is so liberating to feel in control and not a slave to emotions. It isn't as though I don't know that I control how I think and feel and that I am responsible for my decisions and actions (or lack thereof) but sometimes it feels out of a person's control and a reminder or push is necessary!
