Hi there
You certainly are dealing with a lot. I am so sorry you lost your therapist. That must have been very emotionally painful.
In seeking therapy...this is a good step you are taking. What does your therapist say about all this? How about your regular medical doctor?
Is there any information that you need from us here? I am unsure of what you may be asking.
Please do keep writing here if that helps. There are many people here dealing with both physical problems as well as a mood disorder. Nobody can know exactly what you are dealing with but we can share the journey.
Hang in there.
