I think its been about four years for me in therapy. Id hazard a guess that ive had seven or eight different t's in that time and four pdocs. In the beginning i fired the first 3 because they annoyed me in some way. Then the next several left me because they were transferring to a different town and the last one i had to stop seeing because i moved and am too far away. My next t ill see in mid april. I cant imagine staying with one t for more than a year or two, it seems foreign to me. Each one has their own prowess and weakness for things and ive learned from all but one in particular.
