I am with QuietMind in wondering about outside contact if you're doing schema therapy. I am not doing schema therapy, but there are some similar elements in my therapy, and my T allows as much outside contact as I need. But we didn't start out that way, and I think the outside contact rules (or lack thereof) only became formulated once my T knew more about how I operate, what my boudaries are like, how much support I have in my life, etc. Otherwise I think she would be worried about whether she could accomodate the degree of outside contact I am likely to need on an ongoing basis (which has turned out to be a medium-low amount, in typical circumstances).

Have you asked about outside contact, or are you just assuming it isn't going to be offered? I think it's perfectly fine to describe your needs to your T and see what they say. I do agree that outside contact can be important for dealing with certain things, and I hope you are able to get the help that you need, in whatever form that ends up taking.
