Has anyone else lost themselves?

How did you crawl out of it or knock yourself out of it? I feel so delusional lately as to why and how I've become so "bleh." Just completely not like myself at all. I used to be happy and upbeat with hobbies, love, passion for things! Now...nothing. Is this what adulthood is? Surviving day by day with no prospects of happiness or passion returning anytime soon? Art, drawing, make up, reading, music, video games, everything I loved is just not there anymore. Is it the world we live in now that's so much more consumer driven now or am I trippin? Everything around me has changed so much, including myself. So much so that idk who I am anymore or what to do about changing or overcoming it.😔
