A way of helping my sister

I know this is awkward to post some stuff like this, but I really want to help my sister though she's not asking me anything to help her financially I felt what she feel earlier, she's so sad and for sure it's because of financial, knowing that her husband didn't work and also her and they have kids as well. So, I feel pity for her, because I know how it feels when a member of your family is getting sick.

He is my brother in law diagnosed with acute gastro, they are still in the hospital and the problem is both of us can't work because I and my sister has do the alternative to watch my bro in law because the family of my bro in law is both far from us, when my sister went home to sleep a bit then I will be the one to watch my bro in law and vise versa, this night I am here at home, watching their kids.

The amount which I get on this post will go to them, atleast I can help them a little since, they are both not working now because of my brother in law condition, though they have philhealth but the medicine are to buy outside the hospital because they don't have any stock for the antibiotic which taken by my bro in law.
