Well since you are registered with the Office of Disabilities and have consulted professionals on campus, you might have a chance. Do you have any accommodations? For instance, extra time on assignments, reduced course load, single room?
The problem is that it has been awhile , and you have not demonstrated the ability to succeed yet to them. You could take a leave, or leave, and do well somewhere else (community college, online course, as said before) and then reapply or come back according to their criteria.
Is the therapist or O of D advocating for you at all?
