Some feelings may seem predictable in certain situations, but others may be puzzling. Repeated negative thoughts, such as anger, resentment, fear, or depression, may cause our bodies to release the stress hormones cortisol and adrenaline.If you’re working through this book in order, you’ve been spending some time identifying and thinking about feelings.

Or we suffer from disappointed positive thinking, when we expect something positive and it fails to happen, the disappointment that follows can affect us, too. We wonder what has happened to them, and imagine them being hurt or in danger, which triggers anxiety and the release of stress hormones such as cortisol and adrenaline which can cause further hormone and neurotransmitter imbalances.For instance, we may worry that someone we love is in danger, because they don’t come home when they said they would.Many different situations can contribute to negative thinking, encouraging anxiety and other mental health issues.
