I was in therapy with my first T for 6 years and I used to feel kind-of guilty. The only reason I stopped was because the therapy was through the Veteran's Admin and he was sent somewhere else. Stopping was very hard. Looking back, I wish I wouldn't have felt guilty.
I've been with my current T for 2 1/2 years and wish I could be with her for many more. Unfortunately, she'll be 70 next month...I doubt she'll work for more than 2 more years.
I believe that everyone should be in therapy as part of normal medical care.
