I understand this feeling very much. A lot of people feel the same especially since covid. The meaning of life is its the beginning stage where we develop our soul and learn the brunt of our lessons. From a science standpoint life is supposed to be balanced. Half good, half bad. Everything's balanced hot cold, up down, left right but since the pandemic everything is unbalanced and also disproportionately unfair. Wealth gaps, over worked and draining the good from everyone so that a small portion of individuals can have excess good and barely any bad. They cause the vast majority of problems and you in one way or another are probably victim in at least one way. Find purpose in loving the innocence of animals and wild animals who need extra love because they're so neglected by society. Find peace in nature and be one with the universe. It will help I promise. Find a beautiful trail and listen to the birds, bring them food and love them because they aren't rotten like people.
