Someone who has no friends and no social life, who doesn't get along at work and changes places often, who doesn't get along at every place, and who feels like everyone else hates me and looks down on me. I have low self-esteem.
This feeling is mainly because you have low self-esteem. There is no self-confidence is very concerned about the eyes of others and evaluation, fear that their words and deeds can not get the praise and affirmation of others, always suspect that others in the quiet ridicule you, exclude you. In fact, perhaps others did not notice you or did not rest assured.
To change this situation, the fundamental way is to improve their own ability and level, to do everything as best as possible, once something is done well will have a sense of accomplishment, self-confidence will also be enhanced.
Improve yourself one step at a time and don't worry too much about what others think.
