I'm just extremely distrustful of my own thoughts no matter what they are.
I totally relate. I have realized in spades that most of my thinking, when really entrenched in my addiction or PTSD, is completely distorted. No reality what so ever. Sometimes I forget who I am, or where I am (PTSD) and that can be alarming to say the least. I have had that happen for up to about 10 minutes. Talk about panic. Anyway, I digress. I have to question every negative, self defeating, self harming thought I have. I think, for me at least, for now, that is healthy. Not to the point where I'm paralyzed, but where I'm asking myself "Okay, what evidence is there of (fill in the thought)?"
