What would you do if you're fiancè hadn't showered in over a month

My fiancè last showered September 8th. The 10th he went to go visit his older brother (step brother biologically) and he didn't answer so he called him and saw him hanging through his window. He busted the window and cut his brother down. He was then not allowed at the funeral because his brothers biological mother said no even though his mom raised his step brother.... So he never got to say a last goodbye. He's been horribly depressed. He's in grieving counseling but he's still not doing good. He just lies in bed all day.
