You cannot control other people, usually, but you can control yourself and how you react. Just choose to ignore the problem person and focus on the good relationships you appear to have with others. Because others seem to like working with you, the problem is the person you describe, not you. And, if that person is merely a peer, they have no control or influence over you; you may be seeing their inappropriate expressions of their own frustrations or fears around their own inadequacies. Do your own job well, and continue to be compensated accordingly by your employer. This too shall pass.
