I feel much more OK then I had expected this morning.
Think that buying the 'CBT self help book' put me in a fighting mood for my emotional health. The author, William D. Knaus, says: "Depressive thinking is a state of mind, not a concrete reality".
I like that; feelings are reality, but depressive thinking is just that, a state of mind (that I hope to receive control over and at that way reduce my depressed feelings).
I have written down 10 musts out of 12 recommended musts by Knaus and added 2 of my own. I will fight and fight and fight every day to follow these 12 musts for recovery. Some of these 'musts' are recognisable, like getting enough sleep, - enough physical activity, - healthy food, while others are new to me.
