I've been in therapy, with my T, since 1989. We did have a break of about 15 months, but then I went back. It's fine if you want to determine an average number of years that people have therapy, but it's not realistic, in my opinion. Everyone is different, has different issues, etc., so some people may have shorter time periods in therapy than others. I have felt judged by some people because I've been in therapy so long, but the problems didn't happen overnight, so they can't be solved overnight, and I have also been depressed since 1965, though not diagnosed until 1988.
