I know this approach is unpopular. I hope you read my story which is also on here on a previous post because it gives some insight to what I know about depression. Here is my thought process... Is depression from God? Does he give us the depression to deal with? My knowledge of God says no. Furthermore, if it is not from God, biblically that means that it's "not good" or as the bible says "evil" (I don't want to put that label on it because that would definitely not sit well with those who have depression). Here's the thing, I believe in spiritual matters. I myself have seen a demon twice and that demon harassed me for over a year. Later appearing to me through some random person that I met. Furthermore, hopelessness is not in God's character. I personally know that depression is a very common tactic for demonic attack. Yes I know there is a scientific aspect to it, but I also know that in and of itself, the nature of depression is not from God. God can and will heal it, but us as humans have to understand where its coming from and how it affects us in our spiritual life.
I am sorry that you had to go through depression, I went through depression and so many others have as well. I definitely know what it was like as for most of my life I was also suicidal.
Please read my story as well as my series I am writing called "On Demons and The Spiritual". To see a little bit more where I am coming from.
