he has said to me more than once that therapy is meant to be short term. He says he has a few clients for 2 years but they are at the monthly point by then but at the same time, he says but you don't know when you will end yet so don't worry about it,so its confusing.
Everyone goes at their own pace.
People with PTSD often need years of therapy (not always true, though!) to get through everything. Things might keep coming up, and you might need help. Occasionally I go through times when I'm fine with monthly appointments, or even quarterly appointments, but then I go back to weekly. There's no set way to do this.
I personally find that such thinking can be dangerous. These long term problems come from long term issues, many times. There may be unexpected consequences, which only surface years later. My little brother and I shared a therapist in early high school, when I think he was still in middle school (he's a year younger than me). (Was that the right word? Me, not I...?) Our therapist decided that my brother was doing so well that he was going to "graduate" from therapy after only a year. I'm still mad about this. He was absolutely not ready, and my mother trusted a professional over my words and my little brother was miserable for quite a while. Huge temper tantrums, no one to talk to. Too worried to go back to therapy because he had "graduated."
My current therapist is a trauma specialist who knows that research shows that long term therapy can be more productive and more successful for PTSD sufferers. My little brother hasn't even been diagnosed with PTSD, so it's not just PTSD sufferers who need long term assistance.
Some people do need short term therapy only, but not everyone. We're not at a deadline of two years, though. That's silly.
