It really doesn't matter whether she does or does not have a mental disorder. Your feelings are obviously strong, and your reasons sound perfectly legitimate for feeling as you do. Elysium's right only a professional can tell whether she has a mental disorder and what it might be.

But, fwiw, her med list looks frankly dangerous to me - particularly for an alcoholic. That's an overdose waiting to happen. I can't imagine one doctor is prescribing all that knowingly.
