Don't think too much, most people in this life, including you and me, are ordinary people, just living their own lives and arranging things around them. Everyone has different social experiences and life feelings, which also creates different lifestyles for everyone. You don't have to care too much about how others are doing, just mind your own life.
Then, learn to accept the reality that we are only one person, and all we can decide is our own life. Don't try to change other people's things, let alone think that others or society have deceived you. These things are unintentional. Calm yourself down. Feel for yourself, see where you need to change, have a little plan to change, and adapt slowly.
Learn to forget yourself, learn to forget things that make you feel unhappy, think less about things, and laugh more when you are fine.
Smile and be happy. Society; Don't miss the past, don't welcome the future, and don't mix now.
Try to get out of your current life circle, get in touch with other people and things, and slowly integrate yourself into other people's circles. With more people and things, you will know how to live a better life, which may be what you said; Reality has taught people to live.
