I know they say you have to do it, but... since their reasoning is that you need to work through stuff, maybe there is another kind of therapy that would be less intense for you? At least at this particular time. There are, after all, times when we are better equipped to deal and times to back off a bit. It'd be good to ask. It'd at least show that you are cooperative with their goal of trying to work through some stuff, which might make them more inclined to consider alternatives.

Careful with the Lamictal thing. Just sayin'. I've had similar thinking lately, so I "get it", but...(I'm not exactly reknowned for making the best decisions... )
