Hi Mully and welcome, I'm a fairly new member myself. I'm sorry to hear about your worries. You are certainly not the only to react that way to a therapist cancelling appointments because of serious emergency. It's scary. And I get how you are both worried for her and also for yourself (given that you are in the middle of working through some tough stuff).

We open up about our most private and most difficult times to our therapists and so the relationship we develop is very important to us and for it to get interrupted so suddenly it is totally anxiety-provoking.

Be patient and soon you will learn more about the situation. Worst comes to worse, there are other therapists out there for you, and also there is all kinds of medical help available (for your therapist or her family). But it could also be that she returns and things are not as bad as that, and that she can continue. I think your care for her is touching and your concern for your future with her is understandable but don't let yourself get too worried about it. Treat it like anything else that worries you, and calm yourself and tell yourself there are options and things that you or her can do even if things get real bad. Then wait for the news and go from there. Most often things are not as bad we imagine but in the small chance they end up being like that, we will have options and things we can do about them.
