Christian Audio currently has this book for free for download titled How to Battle Depression and Suicidal Thoughts by Ray Comfort.
Here’s the audio book description:
In this moving fictional account, a caring bystander tries to convince a suicidal young man that his life has value and he has much to live for. Through their conversation, you will discover why we all have great worth, everyone has a reason and purpose for living, no situation is ever hopeless, and suicide is never a good option. Whether you want to be able to share these truths with others, or you need to hear them yourself, this impactful book will offer a lasting cure for this growing epidemic.
You do need to sign up to have an account with Christian audio but having an account is free.

Hey Jim, just to clarify. The audiobook is free with a membership. I logged in and found it to be on sale for $5. You can get a free trial membership for 14 days and get it for free that way though.
Thanks for the clarification.
Wow I haven’t downloaded free monthly offer at Christian Audio for a long time and didn’t know that; I was eager to share this resource this morning before downloading it myself so thank you Gene for sharing that.
Thanks for pointing out this resource! I still need to read that counseling booklet I bought on depression.
Glad to hear you picked up that book on depression. Hope it helps as you minister to others
I have settled for the booklet 😊
Not sure about the US but over here it’s a free sign up to a free account with a free book each month.
Awesome! I love Christian audio, I have downloaded but have yet to listen to it:)
