There are a lot of people who think that rejection is like the end of the world. They fail to realize that getting rejected is all part of life. If you do not get rejected, you will not know if there are some things that you should change about yourself so that you can be a better person. It is true that getting rejected will hurt a lot. Some people experience it more often than others.
Each rejection that the person has to go through can make any person stronger. You can learn to be happy with yourself and to explore the various strengths that you have. By knowing what your strengths are, you will also identify your weaknesses. At this point, you will know which things you have to improve about yourself.
We all need to feel a sense of belonging. Once rejection has been experienced, there is a greater need to feel wanted, a greater hesitation about approaching others. Rejection displays that someone does not belong, or so it seems. That's very hurtful. How to overcome your natural reluctance to be hurt again? Firstly you have to be sure that what appears to be rejection is not some problem within the person approached.
Secondly, you have to weigh up what you have to gain by making approaches, and what you have to lose by just staying as you are. Thirdly, you have to consider HOW you are making your approaches. Seek advice on this from friends. You are as worthy as the next person, however powerful they may seem to be. You make your approach sincerely. If rejected, promise yourself you will continue to make approaches elsewhere. Be confident in yourself, once you've made sure, in conversation with friends, that your approaches are reasonable and sincere.
