How long have you been experiencing this? Is it linked perhaps to the coming Spring?

Negative and catastrophic thinking has always been an issue for me but it seems to heighten with the changing of seasons. I have caught myself being rather argumentative more than usual these days. Despite goodness in my life, I too brace myself for something to go wrong and destroy it. The dangerous part is that in the past I have noted this thinking leads to self-sabotaging what is going well.

This is the first thing that came to mind reading your post - is the weather affecting your outlook?
