Big bumps under skin and tiny bumps?

Help.... I have so many bumps under my makeup and tiny ones...my foundation might look dry and Camry because I don't have my usual mostrizer or setting spray which I will get tonight , also the lightening. What will help get rid of these huge bumps. I've had acne since I was 12 but these are huge!!! It's mainly around my jaw and mouth Area and yes I have severe dry skin , dry everything. I have school in a week!!! I dont want these bumps , I'm ok with my scars but bumps... not so much
