Hi Tracie
You can go to any CDC that you want to, regardless of area. The criteria, however, is that they act within our Code of Conduct and see you and monitor you regularly.
As for your existing CDC, if you are not getting on with her then by all means change and you don't have to say anything to her.
However, as a matter of courtesy I would suggest that you give her a bell and say that you have decided not to continue on the program with her and if she asks and you don't feel comfortable explaining your reasons..then you can just say that it's a personal decision!
Good luck with finding an alternative CDC.
