The author Stephanie Foo is a former This American Life producer and a highly respected journalist so when she finds herself with crippling anxiety attacks she investigates why she has them. She discovers that she is suffering from *Complex PTSD* caused by ongoing trauma. She had been abandoned as a child and also suffered from physical abuse and carried the trauma or pain from that with her into adulthood. An achingly beautiful book about an mental disorder that afflicts many. Highly recommend.
