Here are a couple of websites I like:
GET.gg Cognitive Behaviour Therapy Self-Help Resources
www.psychologhytools.org
They have all kinds of things you can download and print off-like worksheets, etc.
There are alot of good books out there, and many libraries have them. Here are some books I've checked out from my local library:
Get It Done When You're Depressed, by Julie A. Fast & John D. Preston
Breaking Free From Depression, by Jesse Wright and Laura W. McCray
