I did not start therapy until I was in my late 30's to 40's. I wish I had started earlier due to many anger/depression issues that affected my parenting abilities. I have, pretty much, been in therapy most of the time since then. I have occasionally taken a brief break ( maybe a month) but usually life throws me a curve and I realize that I have made progress, but still need additional skill building.
There are times I get frustrated and feel like a perpetual mess( mental patient), but I realized as I was contemplating my response that I am gaining new skills to deal with my situations. My therapist knows me very well (we have been together for quite a while) so knows best how to deal with me when I'm being self destructive and uses my own logic skills to get through to me when I'm in a difficult spot.
I don't think break from therapy are a bad decision. Sometimes a bit of distance gives a chance to utilize the skills you have learned.
I hope my post helps a bit.
