One's worth definitely does not depend on comparisons with others, or with what seems popular. There are permanent truths one can grasp and keep, for peace & stability amid the hard times that we all can have; even joy.
I wrote some things at my web site about purpose in life (in profile, no ads or sales), whether one is religious or not. (If you want details and can't find them, you can email me--it is in the site footer.) It revolves around learning (personal growth in ability to serve one's family and others), and service to others. There are important things to learn about the nature of life that also help.
One site that helps with the service part (ie volunteering) is justserve.org , which is free for individuals to participate and/or organizations who could use help, coordinated by location etc. And there are others like it. Unselfish service, helping others in good ways, brings a unique kind of enjoyment and real satisfaction.
I have learned for myself that God is real, cares, life has a purpose and extends before & after this mortality, questions have answers, each person including you is of infinite worth, and you never truly have to be alone. If we learn and make good choices, things can and will be very good, better than now.
All real best wishes.
