Meds: My understanding is that antidepressants require especially careful monitoring when used by adolescents - see this PC article for discussion. If a medical professional diagnoses you with depression and/or anxiety, it is possible a psychiatrist would be more likely to prescribe medications than a primary care physician.

Schooling: If your parents are not up to the demands of homeschooling, a number of other distance-learning or alternative programs may still be open to you. Search for "alternative education," "distance learning" (middle/high school) and "online school."
