I feel so stupid

Lately I’ve just been feeling like I’m stupid and not good at anything. I see everyone around me, and they’re harder workers, more dedicated, and more inquisitive. They seem to care about stuff. I just can’t seem to care about school or really anything for that matter. I don’t even know if it’s depression at this point. I’ve never been diagnosed with anything, but I’ve just been a mess recently for a variety of reasons. I feel like each day I get older, I care less and less about my future. It’s like I see my future slipping away and I’m still in high school. Like if it weren’t for people telling me what to want and what to do, I’d pretty much do nothing at all. Idk I just feel really lost at the moment which is pretty typical of me. I also am super open to making new friends that aren’t incredibly superficial like my own. I want to meet real people, so please comment if you want a new friend. I live in the US btw.
