Common App essay about having minor autism

I plan to write my common app essay for prompt 2, which is about obstacles I have faced. I was diagnosed with PPD-NOS when I was three. However, I have never had any accommodations for it, have always taken the hardest classes my school offers, I have a decent amount of friends, am talkative, and things like that. I plan to approach it by basically saying that while I have this disorder and on the inside it may be harder for me to initiate things like talking to other people, raising my hand in class, and making friends, I have overcome that (broken out of my shell) and have been able throughout high school, to function like a normal high school student.

What do you think of this approach? Is there another way I should approach this topic or should I even use it at all? Thanks.
