I can relate to a large extent in the over analytical department. I have come to the realization that it too is an intrinsic aspect of my personality and can't be removed. Lol
The way I became accepting of myself, loving myself as it be, was to simply observe my mind go through its ruminations, with a type of bystander off handed approach. Not sure if it makes sense the way I'm describing it here, I can definitely expound upon it if you'd care to discuss. But suffice is to say that it took some practice to control when I drive and when I just watch as a passenger, but once I got the hang of it, it was much more organic, free flowing less stress etc. meditation and self hypnosis are some of the techniques I've used in training. Anyway, I'm interested to hear what you think and if you'd like to discuss it further.
