Hi Lmo,
Love your gym analogy, too. I'm too embarrassed to say how long I've been attending therapy. After all this time, I still go through bouts of feeling shame about having to need therapy. It's that whole mental illness stigma thingy that causes it.
Personally, I believe as long as a person continues to gain a better understanding of themselves via therapy, then keep going for it. It's helped me deal with some very difficult life situations. Without it I don't think I would be here today.
Calm (still needs to work on that shame thing)
