So upset with Insensitive Human Beings

Suddenly I feel my life is kinda messy....like everything is not going on smoothly.....like everyone is out to hurt my feelings.....why is that so? What have I actually done wrong to others? I'm already upset as it is due to a recent argument with my loved one...now got to know of another issue of insensitive remarks being commented on me. It hurts. It truly does hurt when the comment is often repeated. Does it make them all the more perfect by giving rude remarks to others? Do they really feel that they are so perfect to hurt people in any manner they like? I wish that these people will realise their mistakes. What satisfaction do they feel in criticising others about the way they look or whatsoever???? What is it? Is it really that funny??? Care to tell me on this? I really wish to stay away from these people......Scram off IDIOTS of the damn lot!!!!!
