>If having a family and being loved are the ultimate goals

>Why care about friends if most people you meet just try to put themselves above you either by pointing out everything they do better then you or downplaying anything you are good at?
"Most" people, and not all act that way. I disagree on that point, they have their own issues and often take it out on you or really anyone. Ever watched plane crash videos, people getting hurt by skateboarding into streetlights? There's a desire there to feel anticipation of pain, but also have the knowledge that you cannot be hurt. People watch these things so they can feel invulnerable, even when others are suffering. It's the same with looking down on others, that person's life is lacking in some way so they put you down. They don't feel the consequnce, yet they get to feel like they made you feel terrible about your enviable situation. It's proof that they want what you have.

>Love and friendship and hapiness are just words used to manipulate you into doing stupid shit others expect from you. They are nothing but vague ideas. Love is nothing but a meme.
It's manipulation if you go along with it. People say lots of things but the truth is that they aren't thinking that much about the effect of their desires. They want to offload the work onto you, everybody does this unconsciously in their words and thinking and it can be difficult to spot. If you don't care about their worries, suddenly you don't "love" them? No, that's bullshit. In order to overcome this, you have to correct them and explain that your feelings are not involved in the situation at hand and that you have your own reasons for doing what you are doing. If you aren't careful, you'll be pulled into someone else's desires and agenda for no possible reward simply because they used words like love, friendship, and happiness when it was really that person trying to satisfy their desires through demands against you.
Happiness is attained through being good company to yourself in your own mind. Often, people have shit people around them so they become shit people in their own minds and then wonder why they cannot handle themselves. It's because your personality is awful at a basic level, and until you take constant steps to remedy this you can not even defend against horrible people like you've described. Self-esteem, self-confidence, etc, all stem from establishing your own desires through actions and reflection upon your wrongs.
Your post is an incorrect reflection of reality, the problem is not that it's true and everyone needs to feel hopeless about it, it's that your opinion and judgement is so lacking that you've become the worst of what you complain about.
Could you offer the ideals you complain don't exist in others to other people? You cannot. First your personality and view of reality have to change before you can even begin to grasp control over others.
