I understand why that would be really overwhelming. It's all happening at once, and we have a tendency to be at constant look-out for abandonments, especially to foresee them and possibly run from them before they hurt us. So in your mind it can nearly feel like some great conspiracy, I know that's at least how I often feel. Like everyone's out to get me and I'm cursed, even though I know that's irrational.
I really hope they are not hinting at that about your wife or you really don't need to mourn the loss of them. I guess all you can do for now is just hang on until you get your new therapists and you get some stability again. Just look at it as moments of ups and downs and you just need to hold on till you get up on your feet again.
