You need more help. Even without your current family problems, you should have had more help.

Insist that other parents step up and join you as mentors next year. Maybe even now to help out with the competition season. If you don't get more volunteers, you won't be able to run the team again.

Also check with your state or regional contact - these people go by several names, such as Lead Mentor or Partner - to see if they know of other engineering mentors that can join you next year.
