I'll send you links from the American Psychological Association later. I replied to your other post though. You could report your T to the licensing board. Her license number should be available online, as it should be public.

I would also report the institution to the licensing board as well, since they lacked finding you an adequate replacement. Waiting 3 months for a T to return is not good for any client, no matter how busy they are, etc. They should have just found you a replacement from the start, and your T should not have placed the burden of her problems on you by telling you specifically what she's struggling with and asking you to wait 3 months for her return. What if she never returns, and you spent all that time waiting? That's not fair to you or your mental health needs.

I'd find a new institution to treat your mental health problems. If it was through a healthcare insurance plan, contact the healthcare insurance as well to see if you can transfer to a different organization. That's horrible what you're struggling with. It's hard for most people to find a therapist, or to afford one, but even harder once you are connected and bonded with a T and then that T just isn't available anymore. I feel bad for the T going through all that she's going through, but the way this has worked out was unethical, it seems.
