The Word of God is truth. (John 17:17) Because it is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness. (2 Timothy 3:16) It cannot be broken. (John 10:35). it is perfect. (Psalms 19:7). The sum of His Word is truth. (Psalms 119:160) The Word of God is SUFFICIENT!
For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete. (2 Corinthians 10:4-6)
We all know that being “CRAZY” [indeed out of mind] is different from “Manic Depression” or Bipolar disorder. This might be direct result of “the fall” [sin] as Jesus says, “His blindness has nothing to do with his sins or his parents’ sins. He is blind so that God’s power might be seen at work in him. (John 9:3) Another is with Lazarus, “this has happened in order to bring glory to God, and it will be the means by which the Son of God will receive glory.” (John 11:4)
Anyway, the Scripture is sufficient to address this issue, so we don’t have to look for other resources to answer this issue [Manic Depression or Bipolar Disorder]

And at the end of the chapter he reminded them this, “Obey the Lord and serve him faithfully with all your heart. Remember the great things he has done for you. But if you continue to sin, you and your king will be destroyed.” (1 Samuel 12:24-25) Saul disobedience: But Saul sinned against the LORD, [he offered “strange” burnt sacrifice]. “That was a foolish thing to do,” Samuel answered. Next is, Saul spared life of Agag and his best animals where Samuel commanded him to kill “all” He disobeyed the LORD again. (1 Samuel 15:3,9)
The consequence of sin; It started when ” The Lord’s spirit left Saul, and an evil spirit sent by the Lord tormented him.” (1 Samuel 16:14).
