Please help, 19 and balding fast

[Scared brat]

I am about to turn 19 in a month, my hairline is terrible and is giving me nightmares to the point that I can't think of anything else. I'm ultra conscious whenever I go out, I wear caps and I'm just straight up scared of my receding hairline.

The hair AROUND the temples looks fine, not much thinning (don't trust me, it's just what I think and hope) but the temple region is just gone, there's nothing left.

Please tell me how serious the situation is, will I be completely bald by the time I'm 25?
