You sound sooo much like me! I've done the exact same thing (missed work/school because I felt off the night before) and the next day feeling like a jerk. You aren't tho OK. I know yous aid you don't want soothing words but really this is a legitimate fear and fear unfortunately makes us do (or not do) things that people w/o the fear would or event hat we want to do.
As for v*ing, if it were to happen I think it would have been last night. Since your step mom was able to help you out and you felt better it was most likely anxiety. You may have felt ill during the day then you get home and can panic so you totally do, I've done this too many times. Like mjewell said the anxiety can make n* worse. I don't know if you are sick or not, there are tons of other things that can make one feel ill but I honestly think if you were going to v* it would have happened. As for work, don't beat yourself up over it. Take today to take it easy and be kind to yourself. Go in tomorrow, apologize and offer to do some extra work to make it up (you know kiss @$$ lol) Also, when you make it thru today w/o v*ing (and you will make it thru) it will serve you later as a reminder that you can feel off and still be OK. Take care!
