What's living?

This question has been going through my head for 2 year and I'm 17 turning 18 in like 5 days. So I don't really have friends and when I was 14 I started cutting myself my mom found out but didn't say anything because she thought I stopped I just moved to my legs where she couldn't see I took the anger out on myself I thought it was because of being myself people wouldn't like me. At 16 I started taking hella pills because I hated living and no one will care but pills never worked now I'm here thinking about what is the point of living when all we do is grow up get a job that we most likely won't like have kid and die what's the point of living? That's the question I asked myself I just feel so depressed and down and don't know what to do I've struggled with being myself for so long and still can't find myself idk what to do tbh..
