Oh boy. I can understand your anger and your confusion about all of this.
At the end of the day though she really doesn't have to reduce her fees or give you more information or anything. At the same time I doubt very much that she is withholding anything from you on purpose. This is real life, there is no master plan, things change, things shift and what we think is secure and unchangeable can be gone in an instant. Nobody can guarantee anything.

Of course you feel angry. Of course you feel abandoned. Of course you feel she "should" do more/charge more/tell you more/share more etc. What is happening is beyond your control and it sucks in so many ways. Of course you have questions. for better or worse you don't even get a say in how she answers them. There is so much to be angry about in this situation.

Your T is one of your main sources of support and she is not going to be available in the same way for quite some time. How can you take control over finding yourself some support in the mean time?
