This sounds very emotionally painful and annoying, and sounds like you are describing facial acne.
Acne is a common skin condition that affects almost all teenagers to some degree. It is caused by the increase in hormones that usually begins in puberty. These hormones affect hair follicles found on the face, chest, back and shoulders. The hair follicles over produce certain oils that cause the follicle to plug or clog up. Also, certain bacteria play a role in the development of acne. These factors all contribute to the bumps and foul smelling pus you are describing.
You should consult your doctor. There are many very effective medications for acne that your doctor could prescribe. Also, your doctor may refer you to a dermatologist who specializes in skin conditions like acne.
In the meantime, try to follow the guidelines listed in the No More Zits question. Do not over wash or scrub your face. This can make the acne worse. Use a mild soap, like Dove and wash your face gently only 2-3 times daily. Do not pick, pop, rub or squeeze the pimples as this can lead to scarring.
