hmm, I wouldnt say I have this problem in social situations, I can chat just fine...the time I think too much is before bed. when I lay down it usually takes a half hour to an hour (on a good night) to fall to sleep unless I am completely exhausted. My mind rambles through a myriad of things both good and bad and I just cant seem to do anything about it except let it run its course.

saying this...I guess its not REALLY a bad thing, except it reduces the amount of time I get to sleep. But I think there comes a point when you really can think too much. That point comes when you get so caught up in your thoughts that it starts to effect your day to day life. I have an example but idk if its really appropriate to go in to it here.
