help me find a movie!!!! pleaseeeeeeee

Heyy everyone,

So maybe about a year ago I watched a movie about a teenager getting mad at his parents (or maybe sneeking out i dont remember) and then dissapearing but hes supposed to be at a friends party. his mother then has an entire search team out for him and at the end it turns out that he was in a car accident. I remember there was one seen about how he was seen with a prostitute or some thing and another seen with a drug trade? i dont really remember.

It seems to be a semi old movie maybe made in the 90's I remember the tittle having somehting to do with a number of days, like the number of days before he dies or something im not sure. Pleaseeeee help me!!!!
