My therapist was drunk during our session.

I have been seeing my therapist for 7 years. I absolutely adore him, I am so comfortable with him, he has seen and helped me through so many phases of life. I do know *some personal information about him, I know he’s an alcoholic but had been sober for many years. 2.5 years ago his husband tragically died in front of him. I’ve worried about him relapsing before, there wasn’t any reason to think he was drinking again, more just concern for him and all he is going through. He lives alone now and does only Telehealth work. Our session today was…. weird. He was slurring, jumping topics without any clear transition, not as involved, saying things that just weren’t like him. He would start down a thought path, stop talking, and then change the subject. He was saying things that I don’t think he would ever say sober and I don’t think are appropriate responses from a therapist. What do I do?
