I feel really upset. Usually I am very obliging to the rudest of people, even when they belittle me. This customer questioned whether what I said was the truth, and I just lost it, and said I was sorry for the inconvenience but the system was wrong and I knew it was the truth! He complained about me. I feel upset because I take so much from everyone but the one time I don't they complained. I am a doormat and something off someone's shoe. I am looking for a new job but there are none. None! How can I stop crying about this? And why am I even crying?
