So you have been with this t for 2.5 years and though you have done some great work together, he is not able nor is he willing to help you with the things that make you feel like you are spiraling out of control. That poses a huge problem for you, I think.

You may just be outgrowing this t. Maybe it is because your needs have changed over time and this t doesn't have the tools to best help you with these new needs. Doesn't make him a bad t at all. It just means that he may not be the best fit for you anymore.

I think supplementing your current therapy is a great idea -- either e-therapy or adding a second t (in person) to the mix. Sounds like you do still get some benefit out of current t, and since you don't want to stop seeing him it may not be a good idea to leave him altogether. Also, can you stop going to group since you hate it and replace that time with a 2nd t?
