I think you have already made up your mind. If this is how you feel, go forth from here, and find the help - comfort - and support it is your are looking for with this other pdoc.

However I will say this, it is never a good idea to burn bridges with anyone, even your current pdoc. You never know when you may have to return to them for help, and you would hate to have bad words lying between you both.

I hope you find the answers you are looking for.
