Why do I feel so underappreciated?

Lately, everyone I know has negative opinion of me, The opinions range from simple ignorance to apathy to hatred and repulsion. It follows me from workplace, college, intimate relationships, and social media. As egotistical as it sounds, I do not think it's me. Maybe it's something to do with the environment, like algorithms changing people's attitude toward others more generally. Maybe most people are feeling disrespected, ignored, underappreciated, etc.
