Answer:
It varies from one person to the next. If you were mistreated as a child, it may have an influence on your personality and you may be afraid of experiencing the same pain later in life. Bullying wouldn't have a major effect on your attitude if it wasn't too abusive or bad. It will make you feel that you will have no friends and that no one is rooting for you, but this is a phase that you may outgrow. This is my own opinion, but different people hold different opinions.
