Unfortunately, it happens to me too, all the time. After some thinking, I realized this is also because of my own behaviour towards myself. If I treat myself and speak about myself well and with respect, I will be getting that from others too.

Unfortunately, we do not live in a perfect world, there will always be someone to insult us and make us feel second class.

This is a reason I've turned my self, my issues to God and His Saints. At least, they help, they love us and never makes us feel unworthy. To God, we are all the same- loveable and worthy.
