PTSDCats, part of the work of therapy can be to help grow you up. Does your T know how to help with that? What you shared of her reaction to this is her commentary and observations that you act young. But how will she help you with this? How has she helped previous clients with a similar issue? There are a number of strategies that can be used. One my T really likes for this type of thing is called Lifespan Integration, but there are other approaches too.
