There are a lot of red flags here in my opinion. I find it concerning that his anxiety was evident enough to his advisor that she suggested he get help. I am also concerned that he “expressed that he cannot trust anyone and he should not have get into this program etc. He is not receptive to see good things came out of it.” It’s hard to say whether this is just his frustration talking or if he’s truly feeling that paranoid and depressed.
I think there are 3 issues here:
- Academic. Graduation is coming soon and he needs to figure out what he needs to do to wrap things up and graduate. Does he need his advisor on board? Is this some sort of program that must be completed? Can he just skate by with this program until graduation? If he needs it then he must either speak with his advisor or the department head and figure out what he needs to go to complete the program. He needs to take responsibility for HIS part in whatever is happening. Laying all the blame on his advisor will likely sound like excuses and I suspect he played a part in it, either due to his anxiety or just because he didn't like or connect with his advisor.
- Anxiety/Mental Health. It's hard to say if your son is just feeling the stress of graduation, next steps, etc. or if he truly has an anxiety disorder/depression. If you think it's the later I would encourage him to have an honest talk with his counselor. If he doesn't like that person, then maybe it's time to look at someone off campus.
- Grad school. Maybe you child needs a break to get his mental health issues under control. I doubt his anxiety will magically disappear in grad school. He has to figure out how to manage it.
Good luck!
