My heart goes out to you. You have so much on your plate. You need the meds you need. Plain and simple.
Continue to request your meds, as any backing off in requesting may be misinterpreted by your parents (that they are correct, you don't need meds).
I hope there's a way to get control of your own meds. Please ask your pdoc, letting him/her know you are denied meds by your parents.
In the meantime, please keep reaching out here and wherever you find helpful.
You are in my thoughts and prayers.
