Thank you Denise (Deejavu) and phillypina for the suggestions on positive thinking and its power!
I was reading some self-help books on depression, having gone through a particularly bad spell. I noticed we all (depressed or not) run "tracks" in our head. They are usually short. For example "I am sad", "I am mad/angry", etc. I thought about it and sure enough I had one playing in my head. I decided to try and change it by being more alert to its presence and then substituting a different one. I always used the same one. "I am happy". I said it aloud when practical (I sure didn't need people thinking I was nuts AND depressed!....lol) and especially repeated it to myself before I went to sleep and upon awakening. Within days I noticed a change in my mood. I am no longer on anti-depressants. I am NOT saying everyone could or should stop taking their meds. I am saying this can't hurt and might help.
Five+ years later I still use this. Anyone with a long term illness has to fight negative thinking from time to time. This is just something that helped me so thought I'd pass it on.
My warm regards to everyone,
