Mental health, is she faking?

Ive known this girl from university for the past 2 years. She has always been very loud and opinionated. when I say loud is when she talks she has to raise her voice so others hear her and turn around. University is stressful, im going through it and let me tell you there are more downs than ups. But some are stronger than others. This girl has been seeing a Psychiatrist for the last 6 months and she would ALWAYS tell everyone about it and the converstations they have. ANYWAYS, today she is sitting beside me and says"my therapists suggested me to drop school an be hospitalized" I was like "ok... just toughen up its all in your head you gotta be strong" (while holding her hands as support) I know its not the best way to answer but then got up off her chair and screamed "WELL YOURE NOT THE ONE WHOS DIAGNOSED WITH MULTIPLE PERSONALITIES DEPRESSION AND ANXIETY" like bitch calm down and take your pills. I know I know its wrong I didnt say that.. but In a way its hard to believe her because when I had depression I didnt talk about it and brag. JUST TO BE CLEAR: She doesnt act like this when we are alone, she does not take any medications (thats what she told me), and Ive seen people with more psychological problems and it shows on them, but this I really think it is bragging. What do you all think?

I just want to say that I posted this to see your opinions and not to be judged on what I said to her (I already admits that it was wrong it was just in the chocking moment). Plus Ive know her but we arent friends, and yes she tells her stories to everyone (even if this is the first time you sat next to her). Thats why I see it very odd.
