I'd again like to highlight the site making changes from Dr. Timothy Sharp, a leading Sydney clinical psychologist. Dr. Sharp makes available free weekly tips (current available here) and you can also register to receive them by email. I enjoy the arrival of the latest tip every Monday morning and find it often helps me to start the week on a positive note. People that I've told about these tips have found also them to be quite helpful.
Dr. Sharp also has a number of help sheets covering topics including insomnia, depression, chronic pain, anxiety and more available here.
Dr. Sharp also offers online therapy, making changes being the first organisation in Australia to have done so, in addition to regular office consultations.
makingchanges, an excellent resource, be sure to check it out.
