Very High Blood Sugar - Type I diabetic & forgot insulin !

hi all i am a type one teenaged diabetic in need of some assistance.

ok so yesterday at lunch, i went to subway and ate there without my insulin, about 5 minutes from home. i started eating and then when i got home, i completely forgot to take my insulin, so at dinner at 7:15, i had a 543 blood sugar. im kinda freaked out right now because i have a race tomorrow (i run cross country for my high school) and ive never been that high before. ive been diabetic for 10 years and i was just wondering for my biggest slipup i can remember in the years ive been diabetic, what are the negative effects of my mistake? i took a lot of insulin to correct it but will my race suffer tomorrow? is there anything else that will happen? i experienced no symptoms before checking it by the way. A sooner response would be best. thank you very much.

hi there
ive been type 1 for 19yrs now and a one off high blood sugar will cause you no probs what so ever long term. It would if you continued to be high. Regarding the running that just depends on how you are feeling. Has the insulin made you feel ok again? If so you will have no problem
