I feel like that sometimes too.
Sometimes I can't tell the difference. There's so much information out there to support that certain forms of mental illness can be counteracted by 'positive thinking' and other types of cognitive resistance or retraining. I start to think I'm doing something wrong, or maybe there's nothing wrong with me after all and I'm just buying into a lie.
But then on the other hand I know how hard I struggle and how hard I've worked to get better, and how despite all these things I still go to scary places at times that are not brought on by 'negative thinking'. So most the time, I just end up confused.
