I relate as well. My "get me through the day" is a silly video game. I usually play on my lunch hour and before I go to bed. I don't watch tv...too depressing. Today I left the game at home and almost went into an anxiety attack. May seem silly to some but when you rely on that one little thing and it isn't there for you it can make for a really difficult day.
I truly am sorry that you are going through this. You will find that a great number of us are or have been there and can lend a listening ear.
