Yah, I have both Autism and Tourrette's...
For your teachers (if you are still in High School), bring up your 504 document (I think it's 504, it's the one that talks of your special needs, if you don't have one, you could probably talk to your counselor about getting one, so that way the teacher don't bug you about it). Basically, this document highlights the special conditions that must be taken when teaching you as a student.... although it may be called something different in another state.
Hmmmm... stories, I have lots of those =D.
I started ticking unconsciously in around 1st grade. It was then I got the 'clear throat' style of tick. I had that for about 4 to 5 years. Another tick I got was in 3rd grade. It was an 'mhm' tick... were I literally couldn't stop murmerring 'mhm'. Got over that one in about a month. Another tick that came up was in 6th grade - the neck jerk tick. I would jerk my neck back hard and eventually it got sore. I eventually stopped - but to this day, I won't do 'neck rolls' in my running stretch sequences for fear of starting over again.
I also take a medication to help control my Tourette's. I remember the first time I took it - in the middle of the day - me and my cousins were going to be going to Disneyland later on that day. However, this medicine made me sleepy. Really sleepy. I woke up about 6 hours later (still at home, they had left me there cuz I was sleeping). Another problem I have had with medication is accidentally overdosing twice (pharmacies keep deciding to change color, and it's not good with my forgetful mind already).
I've explained both Tourrette's and Autism to my peers, so they are pretty understanding, and as I grow older, it gets much, much more difficult to pinpoint the specific 'qualities' which are autistic or Tourrette's-like in me. I don't think if I was reanalyzed now, I would receive the diagnosis again.
