could you clarify-
how old is your friend?
Is your friend suffering from depression, anxiety, schizophrenia etc (if you know/what are the symptoms)?
Good afternoon, and thanks for writing to JA.
You have reason to be concerned, not just from the depression and anxiety - but from what may be hallucinations and/or psychotic behavior.
This being the case, I would urge your friend to go as quickly as possible to an Emergency Room for a psychiatric evaluation. Her behavior may present a danger to self or others which may warrant, at minimum, a stay for observation. It may also warrant intensive treatment on an inpatient basis.
While it would be preferable for you (or family members) to urge your friend to seek an assessment/evaluation, (and accompanying her to the visit would be most helpful!)... if you have serious concerns about her causing harm to herself or someone else, you may want to consider contacting the police or an ambulance. The police may assess her and call an ambulance. In some cases, ambulances will accept a call directly and proceed without police involvement.
It is commendable that you are trying to help your friend but, ultimately, make sure you remain protected yourself, in the event that she is dangerous to others (it doesn't sound like she is at this point, but that may change). Again, if the concerns grow intense enough, and your friend is unwilling to voluntarily go with you or a family member to the ER, your next step may be to call the authorities.
I wish you and your friend the best of luck. Please click <ACCEPT>, unless you have further questions or concerns. Thanks.
