How To Get Rid Of Spots On Face?

i really want to get rid of my spots (i have a few blackheads too). I think they have come about coz i'm a teenager but i dunno. I have always washed my face but suddely...poof and i have loads of spots.

I have tried loads of spot treatments and they won't go. Is there anything you can tell me to do that will decrese them. I am getting so upset and self consious about them i wanna cry every time i look in the mirror and see them.

Anything you tell me i will appriceate so much!! Thank you!!
