Often, we get into a 'tit for tat' situation in which I feel bad about someone else, so they have ill-feeling towards me, which confirms my opinion about them, and so on. Everyone loses out. I need to see very clearly the damage this is doing. Illness often comes when I feel ill-treated or deceived. With strength of mind, I can recover my peace and have positive feelings even towards those who don't feel good about me.
