Driving home I heard this show on NPR radio entitled Invisibilia with a one hour show on Dark Thoughts and how a couple people have struggled with them and got beyond them. I thought it might be of interest to you if you are doing Freudian, CBT, mindfulness or other alternative therapies. Even if you are not in therapy and have thoughts that bother or annoy you, this presentation could offer insights how to go beyond that.

You can listen to the story (an hour or so) and or read it. I think it is very insightful show. If it is too much to read or listen in one night, come back to it. It is a lot to digest at once.
