Get into a really lively christian church, there's a few around, and get hands- laid- on. It may sound old fashioned but it works. The pastor and elders lay-on-hands and pray and The Holy Spirit does the rest. A thousand times better than any library book or medication. Medications can take you to the bottom with health problems and dont fix the trouble... but God does remarkably. Assembly of God is a good church group. Any of the pentecostal/ charismatic churches. Frequently mental problems as in a "voice in the head" are an evil spirit brought in because of sin. Masturbation and sexual immorality are an open door to oppression by evil spirits. Scotland, with its darker side, ought to know about evil spirits.
