I just want to draw attention to a fantastic ACT book I've just finished reading, called 'The Worry Trap', by Chad Lejeune. It's a self-help book on the use of ACT for those with GAD, or for anybody who worries a lot. it's the size of a thin paperback, only 189 pages, and it's choc-a-bloc full of great stuff, written in a really easy-to-read style. He's come up with some great new metaphors (the wrinkle in the sock, art versus ant, the shark infested surfer) and some wonderfully creative defusion strategies, (including 'rhyming your worries', labelling stuff with stick-it notes, and there's even one that involves acting out the worst case scenario with pieces of fruit!!!) The only exercise I can't bring myself to do is mindfulness of a cold shower.
He's also got a really good skills-building section at the end of the book - covering planning, time management, problem-solving, assertiveness etc.
All in all, highly reccomended.
Cheers, Russ
