Therapy is a helping relationship. When it doesn’t go well, it’s often because the therapist has gotten caught in a rerun of other relationships the client has had with others. This is called “transference.” My guess is that something similar (a crisis, drinking, and a relationship “uncertainty” — going south) has happened to you before.
When you are ready I’d talk with your current therapist about how this vignette with her might be similar to other times in your life. Transference is useful when it leads to discussion of what is happening and why as well as what you can do differently. It will not be helpful if you continue to blame her and she refers you to someone else.
Your email is also interesting. Your age and graduate degree would indicate that you have the ability to construct a more coherent and organized letter. Yet, you sent it off as is. I’ve left it in its original form for you to review and reflect on. My best guess is that you have written this under the influence and are looking for a justification of your anger. If that is the case, I would also highly recommend Alcoholics Anonymous. Here is a list of AA sessions so that you can find one near you. The kind of crisis and response you have may be better handled by having ongoing meetings and a sponsor
It might also be useful for you to get a second opinion from another therapist. A second opinion might give you another perspective. If you repeat the same conflicts with the new therapist, you will have further indication that the problem is yours and that you have work to do to learn how to make and maintain a healthy relationship.
