Yes, as has been said, you need some separation. This is harder if you've been promoted and people still consider you an equal, even though you have to tell them what to do. This happened to me - it took me about three months to realise that I couldn't continue the relationships as they were and it took me another month or two after that to make them realise that. Now I don't have the same friendships I used to with them but that's one of the reasons I get paid more. I don't have the time or energy to do my job and pick up their slack myself.
I reward work ethic and initiative with more interesting roles and more overtime. I wouldn't even consider doing that based on race.
