Looking from my experience (but it is your choice for sure), I would:
- Take student from classes now. Leaving him there is aka gambling on my books.
- Ask for incomplete for all classes (you do not lose tuition that way) or ask to complete the ones he is not behind remotely.
- Make an appointment with Psychiatrist now. I am sorry but PCP will not cut here.
- Work with the school to allow to complete incomplete remotely.
- Get meds and accommodations.
- Work on completing incomplete one at a time. Ask to do if over some time (before fall) if possible.
- If you will follow above, most likely your son will be able to come back in fall.
- I will not enroll my child fulltime in Fall even if he would lose scholarship after that experience even on meds. Way to risky.
By sending your child part-time he will progress with studies, will feel that he can do it, will have time and energy to do both school work and participate in EC or whatever he likes to do in that school.
It is super important to have the opportunity to progress and enjoy life in a case like that.
Again that is me, and everyone has a different approach.
