Helpful Fund for my Grandparents

A few weeks ago, my grandparents had an outlet explode in their basement, causing a fire. They have been living in a motel/hotel since, as their entire house needed to be gutted and re-wired. They had to move a lot of stuff into a pod while the house was being fixed. This morning I found out that my grandfather suffered a minor stroke. I feel so helpless, being so far away. With the pandemic, I can't even chance going home for Christmas. I will be sending about $500 to my mom with my next paycheck, to send to my grandparents. However, I don't feel like it will be enough to help. Please, whatever little you can spare would be much appreciated. The funds will be to help pay for the pod, the hotel, hopefully, some medical bills, and for the cost of re-wiring their home (which the insurance is not covering). I sincerely appreciate anything. I'll send whatever is donated when I send over money next week. Thank you.
