I'm balding and I'm only 17

I started noticing that my middle part was a bit wide when I was 14 (my hair was long and I had a middle part haircut) I turned 15 and people started noticing that my part is getting wider, I got a buzz cut when I was 16, to find out the amount of hairs is decreasing and the amount of grey hairs is increasing, now when it grew longer I look like a 30 year old kid, I'm thinking about a buzz cut because long hair with balding made me look ugly asf, but I fear that it would look even worst, what should I do?
