Unfortunately, you have to learn to let him live with his feelings and take care of yourself! Maybe you can look into day care centers for him so you can have a respite for a few hours. Or hire a companion to help you out at least for a few hours a week. Or ask a friend or family member to take him out so you can have a break. As caregiver you can't let his needs make you sick or deprive you of your own sanity. Take some space. Learn to say "no", ask for help. It doesn't make you mean or selfish or uncaring or unloving......it helps you care for you....partly so you can continue to care for him, but mostly because you have your own life and needs too.

It's possible that his demands are a reflection of his anxiety...maybe talk with his MD there may be a medication that might help Sending support❤️
