Negative people can make you lose focus on those good things that you are doing and focus on their negativities. Don’t fight such people, there are enough good people around too. Ignore those ones and focus on the right things of life with the few positive minded people God has blessed you with Good morning.
The mockery and adversity of detractors are disguised tools in the hands of God to force you out of your comfortable zone. If they don't make mockery of you, and they don't spit in your face, and they don't betray you, and they don't stab you in the back, you won't rise and move to the next level. They're for your own good. Look at them from the other side. Accept the challenge and fight your way to the top. DO NOT QUIT. Focus on the top and the top only.
