There is no need for competition, there is no need to try to prove to any that you are better or better, there is no need to try to convince someone to see the good in you, and there is no need to force someone who clearly doesn't want to see and acknowledge to see and acknowledge you.
There is no need to stay in a place or environment where you are not appreciated, valued, and wanted because it is the same strength you push for them to see and appreciate you, it is with the same strength you lose your belief and worth in yourself.
Losing your confidence, self-esteem self-worth, and belief in yourself is a dangerous thing that can happen to anyone in such a position and environment because you will lose yourself and never recognize who you are or what you stand for.
Anyone who for any sort of reason refuses to appreciate you, and value you, will always see a reason to undermine you and reduce your self-esteem and if you stay too long, you could end up believing what they see and say about you. If you don't change them, you will join them.
Don't stay in a toxic environment, in a bid to prove to someone that you are enough, that you are good, that you are better, it can swallow you all up and leave you doubting yourself. I know most of these things are meant to be earned but it shouldn't be at the detriment of your mental health because it wouldn't make much of a difference either.
Don't stay trying to prove a point to anyone, truthfully, nobody cares, move on and continue working on yourself, they will see and believe when the time comes. After all, life is just too short to want to stay in one place trying to prove a point or convince people who may likely never see or notice you. It is not worth it and they are not worth it, nobody with their attitude should dictate how you are supposed to feel.
