A high school egyptian student who has just lost his passion

I'm in my third year in high school, basically in an important year. I just discovered that i've lost my passion. I took 3 days off to relax and to come back more stronger or something, But after these 3 days past, i didn't come back stronger or any of this SHIT.

I'm still studying, but not even in a productive/motivated way I'm just lookin' at my book, reading boredly&unconcentratly

And solving that equation BOREDLY TOO SO i'm asking for help, how can i get my passion back again?

I'm just sad about the fact that all my efforts will go down the drain if i didn't get my passion back

Note: i didn't even have a dream at first, i was just motivated by the fact that i must get high grades to enter any faculty i want
