I'm having dry, flaky, burning, swelling, and itching on the outermost part of my vagina, and my clítoris is red and swollen and it burns?

Likely yeast. do not use OTC meds see your doctor so he can assess your situation it is probably a florid yeast infection that will require diflucan, lotrisone (clotrimazole and betamethasone) cream and domeboro compresses. it will get worse if you don't get treated. do not use vagisil, Monistat etc OTC stuff.
