Fear of losing parents

I have been living alone for the last 11 years and I only spend 1-1.5 months at my home with my parents. And sometimes, I fear a lot about losing my parents and become overly emotional. Generally, I am not a very emotional person, but I guess, living alone has made me a bit emotionally vulnerable. I often sob thinking about some unfortunate events.

In the past, there have been a few minor incidents when I rushed home and stayed there for 1-2 weeks taking care of them. They are not alone, we have a good joint family so there are people to take care of them but I immediately rush home whenever something happens. I don't want to have any regrets for life about not spending enough time being with them when they needed it the most.

This is the harsh reality that everyone has to go some day, but I wish they lived forever.
