I think you have done the right thing by alerting the clinical coordinator know this person needs some assistance.
There is the old saying that says "You can lead a horse to water, but you can't make it drink". People can be a little like that. We can provide others with help and assistance and phone numbers, but if they are unwilling to use them, there is little else we can do.
I had a girl friend who was in great need of mental health care, but she would not listen to anything I had to suggest. Each time I met her, she would go over the same troubles all of the time.
I feel that some people are not happy unless they are grumbling, or they have become so stuck in a rut they do not know how to get out any more.
You have tried to help this person, and well done to you. We sometimes have to cut our extra connection with people if they are dragging us down.
Congratulations to you for being wise enough to know when you have had enough and when you need to back down. It is not like you have left this person floundering as it seems like others are assisting as well.
I hope you do not have to study all weekend and you have some nice distractions and happenings planned.
Cheers for now from Mrs. Dools
