There is a group called Alateen that is a 12 step program fashioned after Alanon and AA. You can find a meeting on line. I wish I had known about this when I was your age. I didn’t start attending Alanon until late in life. You will be amazed at how people will understand how it is to deal with family members with drug and alcohol problems. It won’t answer any medication questions, but may help you not to feel alone and dealing with difficult relationships.
