Is it recommended that she gets Psychological evaluation? Is she in DANGER?

I would definitely recommend seeing a therapist/psychologist ASAP. I suffer from extreme social anxiety and I am constantly worrying about what others think of me and i cant physically stop it. I am no longer able to go to school due to waking up every morning with an excrutiatingly painful migraine caused by my anxiety. I would say stop doing all drugs except for weed. i think that weed is what keeps me happy and healthy ill never stop smoking in my entire life as far as i can see and it can help with the eating and weight problems. But if you feel sort of addicted and start to get desperate for a buzz then just force yourself not to try anything else because that is what starts the gateway drug affect. About the abuse, all i can really say is i feel terribly sorry but the only person who can rlly help u is a therapist/psychologist. And dont be afraid to open up to one and be vulnerable cus thats the only way to fix your problems. Also be patient, the therapist will have to see what in your mind is causing your problems and then they can work from there. They WILL NOT judge you and they will be very supportive. Also if the first therapist you see doesnt help then keep looking. Im on my third one and only til now have i really felt i can truly open up.
