How can i get rid of all my pimples!!?

Im so tired of all the pimples on my face i can hardly take it anymore! I've tried EVERYTHING! nutrogena, noxema, pro-active, clearasil ultra, clean and clear..and none of the products worked. im so self concious about my face now i cant even look at people in school and i dont know what to do anymore. i wash my face every night with clean and clear and i have been puting on the clean and clear acne spot treatment every night and it never seems to work. Please help me..should i see a dermatologist? is it just a phase im going through? what do i do!
