I don’t think it’s fair to accuse someone of attention seeking. Not saying it’s impossible but you really have no way of knowing so it’s best to give her the benefit of the doubt in this situation. If she isn’t legit sick she’ll eventually either grow tired of it or tell on herself.

I always go to the same hospital for inpatient treatment (if they have a bed) but I have flip flopped between outpatient therapists because it’s hard to find one I feel comfortable telling my life to.
