Bloody Wednesday (1987)

The movie circles around a man named Harry (Raymond Elmendorf), an auto mechanic who is going through a nasty little divorce. When Harry gets fired from his job he starts really losing his mind by walking into a church completely naked singing Halleluya. He is committed to a hospital for sometime. When he is released his brother gives him a place to stay, a secluded rundown hotel. It is here that Harry quickly starts losing his mind as he sees ghosts, his life is threatened by street toughs, his teddy bear starts talking to him, etc etc. This all leads up to the obvious disaster at the end.
