You need to realize your value is not a topic of negotiation. You determine what you're worth, you have absolute power to feel good about who you are.
Recognize the fallacy of hierarchy, there is no better or worse, everybody exists on the same plane. We all hold the same worth, despite how it may appear.
Remove all of your judgements and actively work on being grateful for your existence. Gratitude is the antidote you're looking for.
