I have been in therapy now straight for 5 years. and I will most likely be in therapy for some time yet.

A therapist once told me when I asked her when I would be done with therapy that it varies from person to person. the person in therapy and the therapist sets goals when there is nothing more to work on their work together is done. Some people go straight through and take care of their problems and one person doing this can be in therapy just a few sessions and others doing the same exact program for the exact same problem can be in therapy for years. Each person heals at their own pace. Some people also take breaks along the way. depending on how much work was completed before that break means thats less what they need to do when they go back and again that could take a few appointments and others it can be years. again each person heals in their own ways.

Then throwing a little lightness into it told me that when I get off my a-- and take care of everything even if it is just to shut her up so she could not find any more problems was when she would get off my a-- and go back to having a life. LOL

By the way:
Unless you are court mandated or someone under the age of 18 you decide how long you will stay in therapy and with who.
