If you were put on psychotropic drugs, does that mean you are mentally ill?

I realize this a hot button question but a friend and I were discussing this. He says yes; I say that doctors can prescribe at your request or their own decision but that that doesn’t make you mentally ill. For example, I don’t see the occasional Xanax as meaning you have MI. He did qualify it by including depression and anxiety issues, but I still draw the line elsewhere. What say you?
