I understand how you feel. Not everyone wants you to fail but the majority of the world doesn't care if you fail. Your friends are the people who offer you help and who don't want you to fail.

And everything you say is part of the transition to adulthood. I remember feeling exactly as you are feeling right now. The feeling of recognizing the true state of the world and that society really has no purpose or plan for us. And people who do have plans for us are selfish and want us to benefit them or their agenda whether it be political, business or government.

But the only way to play the game is to help others, give gifts to others, contribute to the interests, agenda, or profit of others, particularly when they are your friends so that when you need support you can turn to some of the people you supported in the past.

Reciprocity exists, friendship exists, and some of the smartest people understand cooperation is better than competition when coordination matters.
