Wasn't able to see my dad last weekend because they canceled all flights heading to Newark due to bad weather. I did get to talk to him today over the phone, though, and everyone's prayers seemed to have gotten through. His fever is down, he's eating and drinking again, and he's getting through his physical therapy. He said that he was able to stand up and sit down on his own, which is a big improvement from not being able to even sit up without getting sick the week prior.
I'll update when I hear more news and improvements. Also going to see him during my spring break, which starts March 21.
Thanks for all the support, everyone. My family and I really appreciate it.
