In 2008 I almost died from a very serious medical condition that now needs to be monitored regularly. I have found that I have put my own health care on the back burner, because after taking both my parents for all their medical appointments I really don't feel like worrying about mine.l
Put a sign on your mirror: Remember the big picture! The whole house of cards comes down with you.
Best,
Hap
Please find a way to get some respite and assistance for your situation, it is out there, and no one will feel you are not doing your best because you choose not to make yourself ill in looking after a loved one.
