Is there a possibility of hiring someone to help you either at home or in your business? It sounds like you are doing way too much for one person. You may need helpers to get you to the place that you need to be. If you can't take a vacation from it all, bring in some helpers to give yourself a bit of a respite or just some help. I don't know if I helped but I feel your exhaustion. Do you need a medication change for the depression? I am just throwing some things out. I hope that you find some answers soon. Hang in there and look at what things can help you as opposed to what things can help everyone else. Best wishes.
