I was the one who flunked out of my first (dream) college.
I actually blogged about my experience here.
I would ditto the idea of utilizing campus resources as much as possible.
They not only help with the ADHD, but can help you navigate the specific college in question… where to find resources, professors to avoid, etc.
They can also recommend therapists who have good reputations in the community.
Also, at this point, remember that your role is as a resource.
At this point, an adult college student has to be in the driver’s seat on this one.
