If you mean the habit of thinking negative most of the time no not that I can remember specifically. As for therapy or anything no not anymore. I was going to regular doctor and therapist appointments before, and taking medication, but since I moved in to my own place I've pretty much stopped with all those things. A couple months ago I started seeing a therapist again, but that only lasted a few weeks before I stopped.
So ceasing pretty much any/all professional treatment cold turkey at the same time period of my delusion(s) expanding would have probably been worth mentioning too.
