All my hard work down the drain. Advice?

I may not help you much but I am a mother of two small children as well as a wife and in my senior year of college. I have found that if you do your best that is all you can do, stress just makes you have gray hair early. you will still get into a good college and you will be sucessful in life relax and be a teenager and have some fun before you are 30 with a family and your effort is for them rather than yourself.
