What's the fastest way to get a not psychiatrically clearing me for school? can i get one online?

Call your provider: Psychiatric clearance is usually more difficult to get because the person clearing you is going to want to know the whole history of the problem and how it's been resolved and how you are doing before you can be cleared. The easiest way to get a note is call the person who has been treating you, they already know all of the information and are in the best position to clear you.
