Hi Maryanne38. I believe mental illness (well many forms of mental illnesses) are demonic. I was classified as schizophrenic after doing a 'spiritual awakening' course to work on becoming a clairvoyant/medium (I had no idea how ungodly they are). I was on medication and often the darkness inside completely took over me, so that I had no memory of what I'd said or done etc. God found me at my lowest, saved me and set me free. I stopped the medication, repented my horrific sins, used the name of Jesus Christ consistently to keep the evil 'thoughts' at bay, and converted to Catholicism. Since then, the healing of the sacraments have completely saved me. My mind is so clear and free, it's beautiful. My soul is full and wanting for nothing. I know my mental health issue was completely demonic...and there is only one way to be saved...by our Lord. Please use the name of Jesus Christ everytime you have a 'thought' which is not from you, or from God. Thoughts that are negative, unconcerned fear/worry, doubt, prideful, greedy, confusion, doubt and ungodly are not your thoughts. Living as God designed us, does not include such type of thinking. It is satan who puts these into your head, and mental illness is often a demon within. Please use the name of Jesus Christ whenever you get thoughts like this - he has given us the power to overcome satan and his demons...in his name. My prayers are with you.
