Does this make me a drug addict?

I started taking Ritalin for my ADHD for a couple months and got addicted to it and abused most of if part of the day. And then my parents yelled at me and the forced me to get off of it. Then my pshychiatrist prescribed me Concerta, I abused that too. And now I am on Vyvanse, never abused that because I am not getting the "high" feeling as I did when I been on Ritalin and Concerta. When I don't get a buzz anymore, I would get upset and kind of irritable. So does this make me a drug addict, or not really a true one?
