it's a form of cognitive therapy, involves methods for letting go of negative feelings... just bought the book after work! I'll let you know how it goes!
It's good advice and it's what I'm really trying to do... Just having difficulty with a couple of things and feel like I'm having a permanent panic attack at the moment.
Have been feeling a bit better over the last few days having used my lightbox and had a weekend away in Edinburgh. Not having a good day today though, I've been feeling very low and self critical...
