My father has been doing things to himself due to problems which he believes he has. An example is that he thought he had fungus on his head and started treating his head with peroxide and listerine daily. This went on for some time. Then he convinced himself that the chlorine in our city water was burning him so he began collecting rainwater for washing and drinking. He has a wound on his leg which my mother feels is self inflicted. He refuses to go to the doctor. I feel that there is a larger issue here than just his inured leg. He is also taking 20, yes twenty, ibuprofen tablets daily. I know that this has to end but where do I start?
