My thought is to go to the tests early and talk to the profs. Once you know the options available, you will have to decide how to proceed.

More importantly, it is apparent the counselor is not very helpful. You need help. My thought is for you to contact you general practitioner and get referred to a psychiatrist for evaluation and appropriate treatment.

Many find anathema the thought of taking some time off from school to get better. Even so, going through hell and performing poorly is no fun either. Maybe you should focus on getting better for awhile?

Good luck with whatever you decide.
