Hey. I'm really sorry to hear about your therapist. I know how hard it can be to go so long without talking to someone. Things keep building up, and when you have no one to talk to them about it gets really depressing and lonely.
But I think you should give talking to the other therapist a try if you start to feel down. Even if they're not the perfect match, they may be able to help a little bit until your T comes back. A little help is better than none, right?
Best of luck to you, hope everything works out in your favor.
