Hi Stuart,
I didn’t go to GMA myself so can’t answer your questions, hopefully DL0708 will.
My own advice though would be to contact GMA regarding the practicalities, what to take etc, and ask them. You can get contact details here…..
With regards the rest of i, the best thing to do is probably just to go with an open mind and soak up all the support and tools they give you. Sometimes going with too many expectations/pre – conceptions isn’t a good thing – just go with that open mind and absorb the support that will help you move forward in recovery.
In the meantime you might also want to conect to the groups here and start getting support in the My Journal Forum as well.
