I am so sorry that you are having to go through this. I do believe that most, if not all, mental illness is demonic in origin.
Little by little, your husband looked to things of the world for relieve of his emotional pain, instead of crying out to God, and receiving the peace and joy of knowing that God works all things out for the good of those who love Him.
We walk a narrow path as Christians. To stay on that path, we need to keep our eyes clearly fixed ahead to our reward and our Savior, Jesus Christ. Often, Satan attacks us by throwing something in that path. Our eyes are diverted, even if just a little bit. Now, this could be with a problem, an illness, a loss, etc, or it could be something of the world that we enjoy, such as a tv program, etc. As our eyes fix upon it, Satan turns it, just a little. Our eyes turn with it. This continues, until suddenly the goal of Heaven and the Face of Jesus is no longer visible. Then we wonder how we got to this point in our lives.
We seldom fall into sin rapidly. Usually, it happens in small increments. I believe that is what happened to your husband.
I do believe that those of us who are saved still experience demonic attacks.
Medication can correct any chemical imbalances, but most people are left with a "flat" feeling that is not appealing to them. Thus, many don't stay on their meds. I think, again, this is demonic in origin.
In the end, I think that prayer and laying on of hands is better than anything man can do. You also need the support of your friends, church family, and family, because it is easy to get discouraged and lose your joy in the Lord.
I don't know how all this will end for you and your husband, but if he is saved, then he will not be snatched from the hand of God. We can't see the end of this dark period, or how anything good can possibly come from it, but God HAS promised that all things work for good for those who love Him, so something good will come from this. You can believe in God's faithfulness and cling to this promise.
God bless you and your husband. You will be in my prayers.
