Nice that you are being paid well, Ask yourself do you deserve it, if yes be happy and enjoy it, certainly people will feel differently about it, they aslo will know your worth and accept it in due course, you can not shut every talking mouth and should not make an effort also, but certainly you can be calm , cool collect and befitting your position and make no foes intentionally,best way is to maintain relationship on a balance not too close not too far , may be time and experience will help you learn, this is a common problem I see during my training programs for manufaturing units where old time time tested labour force has been pitched against new technical graduates, experience against graduation.
certainly a task to recon with, I am sure you will pull through, all the best.
