Half my life / Diana Noonan.

Katy struggles with anxiety and compulsive behaviour disorders. She self-harms and is seeing a counsellor. When she starts dating it only increases her anxieties. Then her parents hear her Yiayia (grandmother) is ill in Greece and maybe dying. The family decide to visit. Reluctant at first Katy eventually decides to embrace the trip as a way to learn about her Greek family but the visit uncovers some dark family secrets. A novel that explores the fragility of families, and the damage that can be wrought when unresolved issues of one generation shape the lives of the next. Also a story about hope, and the ability of families to survive and heal damaged relationships.
