What's the point of living if my life sucks?

I've never talked about my private life here on reddit but I want to vent. Saying that i'm stressed would be an understatement, there's the risk that I'll fail this school year because I didn't study enough and I don't have any real friends so I never hang out with anyone. My life is very repetitive and I don't even have any hobbies so i stay on my phone nearly all day, I feel like everyone my age is better than me in everything

EDIT: thanks everyone for your advice and support, I really appreciated it! Unfortunately I couldn't respond to any comments because in the last few hours I was very busy
