I was in therapy for 9 years and moved to another state and got married so terminated :-) and then 9 years later I started again with the same therapist (her situation had changed too) for another nine years 1996-2005 and just terminated a couple summers ago when we both retired. I told her I was going to start therapy again in 2014 to keep the 9 year "plan" going :-) I will be 64 in 2014. If therapy helps, then it helps! But there is a big difference in how you feel now and how you and your therapist might feel in a few years and, theoretically, therapy is to help with "real" life and one should be getting more involved there and better functioning, etc. I guess the necessity in quitting therapy is a little like the necessity of not being a "professional student" :-) and never getting a "real" job but just going on for more and more schooling.
