People?

People disappoint me often. No one is quite as kind, attentive, emotionally present, available, compassionate, generous, or polite as I want them to be. I put so much into making people feel seen that I often feel invisible by comparison. If I stopped caring for a day would someone assume my role or would I be left in the dust? Would they grow closer if I drew quieter? What can I do for people; what can people do for me? Is everyone just selfish? I don't understand why I feel like this or maybe why other people make me feel like this. I want things to be better.
