The longest I've been with a T is 4 years. But I've been in and out of therapy for 24 years. I don't know if I would define my issues as severe. Probably not. I know people who have had to deal with much worse. I don't think I'll be in therapy for the rest of my life. But there isn't an end insight right now. And I'm hoping that T will still be there even when I no longer need her.
