Is it normal to feel like nothing matters
I went through this whole existential phase a while ago and I wanna know if this is normal or not: I feel like nothing and life matters and it is a good and bad thing for me. I'm usually very awkward and shy but when I think back to what I believe "nothing matters in the grand scheme of things" I feel really courageous and outgoing. I feel like I can talk to any girl and try new things and I feel really confident. On the other hand when I think that nothing matters it makes me sad because everyone I will ever love will die. Everything I do is meaningless because it'll all end and I'll be forgotten. Then I think if everything is meaningless that means everything is potentially meaningful because I can give things personal meaning? I don't feel suicidal, but I don't feel motivated. I feel lazy and forever unfulfilled. I feel like pleasure and happiness are the only things I live for, is that ok? Should I live to serve mankind and be a valuable member of society? Or should I live carefree? Or maybe both? Is it normal to think this way as a teenager?
