self sabotage

I’m struggling with something. That is that I have uncovered this new belief that I have. That I don’t want “them to win.” When it comes to my goals, I always self sabotage myself because I keep thinking I don’t want them to win. “Them” referring to everyone in my life who has told me that I’m not good enough until I achieve XYZ. So every time I get close to achieving my goal, it’s almost like I try and rebel and feel like I don’t want to have to please others to be worthy. The goals I set are for ME, but I still get this feeling that, if I achieve the goal, then it proves that they were right. Please help coach me on this.
