I'm 24, and I've had SA for about 8 years. I was in Grade 9 when I had my first panic attack. I'd been getting picked on a lot by my friends about "conforming," which was really just a defense mechanism to stop a larger group of more violent classmates from picking on me. I started to mimic the things they did and parrot their ideas, and it earned me acceptance from them, but in the process I ended up pushing some of my good friends away.
One day, a good friend started pushing me, accusing me of acting "Weird" in front of a good deal of my classmates. It was one of very few times in my life that someone who I valued and considered to be a friend started to lash out at me, and this time ended up being one too many. Rather than fighting back or trying to explain myself, I froze up, started to hyperventilate, and then went into an inexplicable crying fit. Things got awkward with my friends after that, but they were at least understanding about it. It reminded me of who my real friends were.
