Some people will be happy for you only until you pass them. Don’t slow down to keep them comfortable.

Support is often genuine and conditional at the same time, with the condition being that the gap stays roughly where it is. People can want good things for you right up to the point where your progress changes how they see their own, which is uncomfortable rather than evil. Recognising it early saves you from taking it personally later.

Watch who gets quieter as things start going well for you. Do not confront them and do not adjust your pace. Move your attention toward the ones who were glad about the part that gained them nothing.
