The awful spiral...feel bad and then feel guilty about feeling bad...feed worse etc.
I agree. It's best to accept the way you feel and not try to argue with yourself about it. Then, if you can, set it aside and start by doing one thing. For example, mornings come when I do not want to do anything, go anywhere. I start by getting out of bed. It sounds so ridiculous but sometimes that is a major accomplishment. I don't think beyond that until I am standing next to the bed. Next step might be take a shower or brush my teeth and that's all I think about until it's done. Step by step, little by little. There are days when I have the ability to stop anywhere along the process. Other days when there are things I have to do I inch my way along, breaking everything up into manageable little pieces.
Sometimes I curse the process but usually when I accomplish something, no matter how insignificant it may seem, I feel a little better. Sometimes just getting up and getting moving will lighten my mood a bit.
