Sometimes we give the authority to others to judge us. And they count our creditability through our failures and successes in our life. Doesn't matter what kind of person you are, how is your nature, what you think about others? How to deal with another person, nothing. Sometimes the person who is expert in showing off takes the advance but don't worry it will be temporary because he never copies your personality. So believe in you, your honesty and never give up to improve yourselves rest will be sorted out as the time will pass.
