Hi M.,
WOW, your DD sounds exactly like my 8 yr old DD. My DD is also a big time perfectionist which sometimes causes her to be slower than her class mates because she's so worried about her work not looking perfect! Your DD sounds like she needs something for her nerves as well, not just for acid indigestion.
When I was in school and got nervous, sometimes I'd get so upset I started skipping class or faking an illness just to stay home. I was popular, had good friends, made good grades but NEVER felt comfortable going to school but it only got bad when I was in High school. Every morning my stomach would ache and I'd get the butterflies in my tummy while driving to school.
I read recently that social anxiety is the # 1 mental illness in people and I find that to be very true for me. My mom would take me to doctors and I remember taking a med to help me sleep at night and another one called Paxil to help with school issues and anxiety but the Paxil didn't make any difference.
Thinking back, I do wish my mom had taken me to more doctors to see what else could work for me because the stress of school was literally taking over my life. I want more than anything to attend a college but the fear of going back to school makes my stomach ache and unfortunately prevents me from getting a better education.
I have a very outgoing personality and was always the crazy goofy one of the family but I seemed to never be able to show that at school. I have never discussed this with my DD but I see her repeating some of the same nervous behaviors I did as a child. Every morning her tummy starts aching before she leaves and at the last minute she'll say "I have to go potty" which I know is from nerves.
I'm considering having my DD evaluated for social anxiety and going from there. I highly recommend you doing the same for your DD. You don't want her to have such a fear of school that she wants to skip class or ever play hooky. If she's as bad as I was and it sounds like she might be, then it will only get worse.
If anything, try getting her into some counseling and find out where her fear is coming from.
Good luck to you. I wish both you and your DD the best!
