Lowboy by John Wray. 

William Heller, aka Lowboy, is on the run after breaking his conditions of release from Bellevue psychiatric hospital.  He travels the subways and subterranean tunnels, off his medication and becoming increasingly psychotic as his paranoid schizophrenia takes over tipping the human need to find patterns in the chaotic into madness.  Wray writes the novel from two points of view, Lowboy's increasingly disturbed perspective and that of Detective Ali Lateef, searching for Lowboy with his mother Yda, aka Violet, their tale too becoming unspooled as Lateef reflects on his altered identity, name changed when his father converted to Islam, and that of Yda.  Very good, but I prefer Tabitha Suzuma

The Trick is to Keep Breathing by Janice Galloway

How can you heart keep beating when the man you love is dead, a man who you're not even permitted to grieve for because although he had left his wife it is she who claims his body and is named at the funeral. This is the story of the ironically named Joy 'lasting' this ordeal after her lover drowns, her complete breakdown in the face of the shattering of her world consigning her to a psychiatric ward, and the men and women who love her and despite her continue to reach her. Reveals the true horror of grief and the dangers of wrapping a life around a single person. Deeply moving, Galloway traces a narrative through a blasted emotional landscape with skill and feeling.

Molecules of Emotion: Why you feel the way you feel by Candace B Pert

AZ: "As a graduate student in 1972, the author was part of the team that discovered the brain's opiate receptors. In this text, she provides an in-depth look at the science that led to this and other findings, such as the fact that similar receptors exist in the glands, spleen, bone marrow and other organs, which convey information in both directions via "neuropeptides" to all parts of the body. The author argues that this complex communications network invalidates the distinctions between mind and body"

Brilliant, I understood a little about neurotransmitters and thought I understood that SSRIs inhibit retaike because that is where most bodily communicatin takes place, but Pert's discovery that neurotransmitters and other bodily drugs dock bodywide affecting vastly separated organs and systems was a revelation. It helped me make sense of the need for a holistic approach to bodily health and makes me more determined than ever to find a balance.
