Don't let your past ruin your future
Some people have been so burned in their past that it gets in way of the future. It even ruins relationships.
Bullying and getting robbed of happiness can have an effect on people. Some may have got over it but deep down inside they are suffering from low self-esteem.
If you are one of these people, try to get your self-esteem up. Look in the mirror and say "People can like me." Just because you have been hurt in the past, does not mean that others will. If you let your past get in the way of your present, you could have a lonely future.
