I understand your desire to stay involved with the team, but you need to take care of yourself before you can take care of others.

Perhaps another established team in your area would "lend" you an experienced mentor for a year or two. Many teams have good 2nd string leadership that might like to try a turn at the helm. Perhaps the teams could collaborate to some extent. You wouldn't need to share build space or make the same hardware, but it would ease the learning curve for the "new" chief mentor and improve the experience for all involved.
