Accused of cheating by proctor due to information on scrap sheet Sorry if this is a bit long. I took a final for an intro elective (I'm a college senior), a pretty easy A- GPA booster class (average before this final was 90+). 

I have learning disorders so I get to take the exam in a private room. Shortly into the exam, I asked to take a bathroom break and grabbed tissue from the washroom. Then I went back into the exam room and continued, got carried away and started doodling on one of the tissue papers. I believe I wrote about three words on the sheet before the proctor came by and asked why I had unauthorized "notes". I explained that these weren't notes and just me doodling. He asked why I didn't doodle on my scrap and I said I was using my one scrap sheet for actual calculations and didn't want to run out of space on it. He said ok but that we would need to go to the head proctor and report it just in case, and if she was fine with it I could keep writing. He gave me back the papers and we got up to head out to her office.

Once out of the exam rooms, he said on a second thought to give him the papers instead and he wanted to hand them to her. I said no, sorry, I can't do that, we are already heading there, whats the big deal with me holding them? He said something about protocol, but I told him I didn't feel comfortable with handing him my papers.

He then tried to grab them from me, which was when I ran into the bathroom because I felt like he was trying to attack me (been raped before - guess I got triggered). He goes into the bathroom with me still trying to grab my papers. I ran out telling him to get another proctor because I am feeling harassed and uncomfortable, so I went into the next washroom and he followed me in there. I had a panic attack, and ran out again trying to get as far away from him as possible, that was when he called a female proctor who sat with me the entire time in the hallways till they brought a counselor. Now he claims that I cheated with unauthorized notes and I have to go to a meeting with the dean. 

Also they are bringing as evidence my scrap sheet because I had previously been given the same exam but couldn't complete it due to being sick (I memorized a keyword from each question wanting to see (also kind of hoping)  if they would administer the exact same exam and matched the old questions to the new ones). I don't see how that has anything to do with the three words I wrote on the other sheet.
I'm sorry, but it looks like it will be impossible to prove your innocence under these conditions.  You refused to follow the instructions of the proctor because you "didn't feel comfortable with handing him [your] papers" (which is not a sufficient explanation), and later failed to control your emotions and ran into the washroom as if you were trying to get rid of some evidence.
