I have also discovered that the worst days can get better. Lots of times I over think the bad stuff. I have read that we should think of things we are grateful for in bad times. But, I'm prone to depression. I don't do well with the gratitude thing when I'm really depressed. The only thing that seems to help is time. Time being hugged by my honey. Time actually accomplishing something. Time spent in my closet making it neater. Time spent outside just breathing. Time talking to a friend or my kids. Time planning something good. Oh, and good food.
I'm working on finding a sure fire method of ridding myself of depression. I'll take any help you can give me.
