@speedycaracol-You are probably not in trouble but, since you're a recruited athlete, it wouldn't hurt to write to the coach and tell him/her what you've said here. Mention that you bit off more than you can chew with the job, school, and soccer and that you're working to get your equilibrium. Ask if the coach anticipates any problem with the admission office. I think the answer will be no, but you'll get more accurate information from the coach than you will from me.
@Mareekah -If you or your husband--the boy's parents--attended college, then your son will not be considered 'First Gen" because he grew up in a household with college-educated parents, regardless of his birth parents' backgrounds. However, he may be eligible for diversity scholarships at some of his target colleges. Not all colleges, however, offer these scholarships but some do.
@hoshjoshe -Congratulations on your Harvard acceptance but condolences on your loss.
You probably should write to Harvard now and explain any possible downturn. But before you do, send me a private message and let me know more about the loss and how it's affected you. Then I can advise you as to whether you should contact Harvard before you hear from them (and you may not hear from them but it's very possible with such a downturn).
