I know it can be rough. Many mentors / coaches and students put in hundreds of hours in 6 weeks. How many other adults are helping you? Why two teams? It would be hard to see a team fail by stepping back but it may be necessary. Is the team part of a school district? Can you find others to lessen the load? You shouldn't need to get too burned out on something you enjoy. This can be something you want to do for many years to come.
Best of luck..
Maybe there needs to be a mentor support group
