Ouch ouch ouch. It may not seem like to have time in the day or the energy, but it's worth making time to take up some form of exercise. Something regular that gets you out of the house would be ideal. I find this helps with sleep quality, energy and general gloom. Get those endorphins running around. Swim, boxercise, zumba, whatever.

You are way more important than your house, so do take time to fix yourself.

Is there anyone you can ask to have a talk with your son? And like Limey says, you clearly need help with your parents.

I wish i was closer and could come and help.

Would it do any harm/would you be able to tell your son that you are passing the responsibility of shopping for your parents and/or chauffering your parents on to him in a way that makes it clear it's final. Sometimes useless people surprise us by stepping up when we give them no choice.
