Something to think about, the feeling of waiting 2 weeks to talk about things brought up in therapy is different than knowing there's no one to have to open up to at the moment. At least for me, there's more frustration knowing things are stored up and I have to put them away for a while just to struggle to open them up again in a week or two. I find it easier to deal with things when they get stirred up, not in having to constantly open them up and put them away again...
however, that's just me. Also, as someone mentioned, every other week is easier to start with then to switch to (unless you have gotten to a point in therapy where that feels natural and workable)...
