As you said, you are in complete control of your life right now, since you are of legal age. I on the other hand am not so lucky. What I would suggest doing is going to your doctor and just talking about it. Just going to the doctor does not require you to get prescriptions for things. Doctors have a stigma of only giving prescriptions, but they are also there to give reccomendations. They may not even suggest pills, they might suggest a physical activity or something to do in place of, and you can go in there saying, hey, I don't want to take pills for this, but what else can I do.
Here you might be able to help me out, I am struggling to tell my parents about my depression, what did you do and how did your parents react?
