Actually, I think even if someone loves and cares for you, they may be in denial about a health condition and totally disregard it. This is true for physical as well as mental illness. I watched my dad argue constantly with my mom about not being able to keep the house as he wanted, despite her declining health when she had cancer. Many years after her death he realized how wrong that was of him to be on her case all the time when she could barely even get out of bed, but he didn't want to believe she was sick.
