There are times when you will feel bored or depressed or just plain anxious. There will also be periods of extreme sadness or frustration, especially if you are going through a divorce or a job loss. This is the time you need to help yourself and not give up.
A book I found very useful is “Feeling Good” by David D Burns, MD. It will show you what are the basics of depression you need to be aware of. It will also teach you the warning signs of depression.
It has lots of exercises to get you out of depression. You can even measure your levels of depression, and chart your progress.
I highly recommend this book as a companion to professional help. It also gives you the threshold level of depression beyond which you need to take professional help.
I also suggest you buy the handbook too.
These books can save your life or the life of your loved one!
