I haven't had a therapist who told me their problems so I wouldn't know if a therapist had a problem or not. I guess if I had an eating disorder I was in therapy for and the therapist was obese or looked too thin to me, I'd not want them for my therapist but unless a therapist had "obvious" other problems, were depressed seeming or anxious, etc. I wouldn't mind if they were obese or too thin if I was there for something other than an eating disorder.
