It sounds like you are suffering alone, which is difficult, and possible. Some possible things that could help are the standard responses, get outside , exercise for 5 minutes or more, write how you feel, learn something new, make a goal, or even talk to someone as a friend that you feel is supportive.

Anything you can do to support yourself is amazing, and supportive to your family as well. And you know your situation best, keep that in mind.
