Have you discussed any of this with your current? It might be worth it to get her take on it.

Overall, perhaps it would be better to start over fresh. You could get the help you really need, and at a good price for you. To me, it's a win-win. However, I would discuss things with your current therapist. It's worth a shot, right? especially knowing that the worst that could happen is you do choose to discontinue seeing her.
