1. Falling in love easily
Of all the struggles an overly nice person has to face, falling in love has to be the one that hurts the most. Since you are the kind hearted person who always go the extra mile, falling in love is very dangerous for you. Once you start to like somebody, you will do almost everything to make that person happy. Their happiness becomes you happiness. Why? Because you genuinely care about them. Your personality is such that you will make your beloved the top priority even if it meant having to readjust your whole life. While this is an admirable trait, the downside is when the relationship or even marriage comes crashing down. Maybe the person you did all these for did not feel the same way about you. Maybe your over attachment made them feel suffocated and the relationship had to end. Thus, you are left feeling devastated and keep wondering what is wrong with you.
