Not really. I wish I had positive thoughts....I WISH! I wish I didn't have obsessive thoughts with certain people or feelings of self-doubt...but I'm plagued with these thoughts a lot of the time. And I don't know how to stop them (do you have advice?)...the only time when they're not bothering me is when I'm very, very comfortable with my surroundings, interacting with everyone and feeling in control...if anything goes wrong, my mind just misfires and the thoughts come back again...kind of like emotional ADHD...
I might look into CBT (cognitive behavioral therapy) to deal with this, but I doubt things will change. My mode of thought right now is a result of 20 years of cognitive conditioning...I can't just change at the snap of a finger. Then again, that's no excuse to not try to change.
