I have been reading this entire thread and been wondering what kind of therapist would "abandoned" a client who most certainly could benefit from continued therapy just because you emailed her, sent an angry letter or SI, is no reason to terminate you. That would be up to you if you truly wanted that. I have seen my therapist for almost 20 years for a multitude of issues one being abandonment issues stemming from early childhood. I have felt the same pain you have felt when an appointment had been canceled or a session missed. I know this comes from my issues and not her not caring about me. I have always been able to send her a letter(s) between sessions or call her if I need to. I can count on one hand the times I have felt anger toward her regarding abandonment issues and she has encouraged me to express to her those emotions. I sure hope you can get your feelings out to her and reconnect if that is what you choose to do.
