Hello. I know how you feel. It can be very overwhelming when you’re the only caregiver to many. First of all, remember that not everything needs to be done at once, so prioritise your time well.
Secondly, every person- including those you are caring for- is accountable for his actions. So feel free to delegate responsibility, like homework to kids, taking meds to older folks, and bedtime to everyone. It may be hard at first as they push boundaries, but you have to let them fail first and let them try again.
Lastly, don’t forget to take care of yourself. If you need to schedule personal time for yourself, do so. It should rank as highly as tuition class for kids. Don’t wait for a complete breakdown before declaring you need emergency rest, otherwise that ‘MC’ will affect even more people. Schedule rest regularly so things can go as planned (as much as possible anyway).
