It's completely easy if you know the limit of yourself. To respect other people, you need to respect yourself first.
The only trouble is when you loose your faith about every little thing. When you loose the benefit of being what you are. But it can be worst when someone makes you feel such as an unfaith person.
So, in this case, you have to come back two steps and look for what you've been doing with yourself. It's important to be real and sincere with what you wants to be. Because to represent something you need to believe on it before.
That's the only way for emancipate respect with you and with every person that would love to judge you.
