I went thru something similar with my husband and some here offered to pay us through paypal for sbd we sent them from our wallet. That way we didn't have to power down and we got the money very quickly. Perhaps @steemitbloggers (@jaynie) can put the word out to anyone willing to do that?
I don't have much to give, but I'm sending you a few sbd to help. I'm so sorry that you are going through this right now, but I'm sure people here will help ease your burden a bit. Praying for your grandmother and your family. Please take care of yourself too! Sending big internet hugs your way!
