@philbegas, I don’t know about getting a permit. Sometimes I speak for NAMI Maine, and my co-presenter has a dog who she can ask if something/someone is real or not! The dog signals differently depending on the answer. It took over a year to train him.
Yes, that’s my Australian shepherd. Best dog ever. It’s such a sweet, smart breed.
I figure there’s different levels. If simply having the presence of a furry friend is enough then one could make due with a calm animal. If advanced training is necessary to sense whether an attack is life-threatening, etc then I understand why there would be a waiting list.
I love Aussies. My allergies don’t though 
If the person is a danger to themselves, that’s an emergency, call 911, now.
Otherwise, I think I would stay out of it because you are not a professional and don’t know what you are doing - you could do damage. Seek therapy for yourself if you want, or seek help from a dean, or move out.
The only way you are equipped to intervene is by calling a professional.
^Agree with all of that.
Right now go to the Counseling Center and tell them about your roommate…you want help on what you can do and how she can get help.
It occurs to me that if you call 911/administration then perhaps her parents will become aware/involved. That is a good thing to my way of thinking. We don’t know the underlying situation but this may be something they have dealt with before.
If you are in university owned housing then your RA or housing director would be a good place to start. If not, then the counseling center should be able to help. Another possible adult to alert is the Dean of Students.
In this type of situation, I feel that the best course is to alert the people who are (or should be) trained to evaluate the person and determine the best course of action. Until you have this issue or have live with someone who has it, it is very difficult to know the best way to approach and help someone.
The counseling center can also help you deal with how this is impacting you. I suspect you might feel that you are betraying her by contacting others for help. That is not the case. Your roommate sounds like she has an issue that has gone beyond her ability to cope. I admire that you are doing the right thing by trying to get her help. However after that your role (if possible) is to be supportive and a friend and let trained professors handle the underlining problems.
Unfortunately, you will probably need to request a room change or move. Until your roommate gets help, the situation is likely to get worst and become more stressful for you. While you may feel you are abandoning her, you need to take care of yourself.
