What do WE want from people?

Why is there a need to have friends or wanting comfort when one's feeling down, yet not letting anyone reach out, or thinking if they REALLY want to do that for you? Why is there love between people? Are we all selfish? Or is this how we were made to think? Is this just our "built in" thought? Or can we actually live without these things if we try?

These are just my own random thoughts. 😅
