I am so sorry, Abby. Do you receive medical treatment as well? Your symptoms sound like the ones I have when in a deep depression. I have to survive on medicine, not to say it is for everyone. I also receive therapy and the two together keep me somewhat able to function normally.
Have you asked your t about possible other therapies you can receive elsewhere if talk therapy alone isn't working? Is she trained in other therapies? If she is just handing you books to read, it sounds like she is not trained in other methods.
I hope you will be able to explore other options that will work for you.
