If you have fear of some pain or suffering , you should examine whether there is anything you can do about it. If you can , there is no need to worry about it; if you cannot do anything , then also there is no need to worry

When others insult, rebuke and speak unpleasant words to us, although an intolerable pain arises like a thorn at the heart, is we comprehend the teachings then we can recognize the essence less nature of these words which resembles an echo. So just as when as inanimate object is scolded, we will experience not the slightest mental turmoil. --dalai lama

If you know that someone is speaking badly of you behind your back, and if you react to that negativity with a feeling of hurt, the you destroy your own peace of mind. One's pain is one's own creation. One should treat such things as if they are behind one's ear. In other words, just brush them aside. To a large extent, whether or not one suffers pain depends on how one responds to a given situation. What makes a difference is whether or not one is too sensitive and takes things too seriously --dalai lama,
