That sucks, sending you some positive vibes for sure.
My grandma is in the hospital again for the second time in the past 6 months, last year she fell and hit her head, had to relearn how to walk again, got some minor brain surgery to drain the blood in her brain.... Seemed like she wasn't going to make it for a while.
She broke her pelvis today, no idea how bad it is or whats going on but she's going to be in the hospital for at least a month. Really hoping she pulls through all of this.
Seriously though, I feel you. +K, good vibes, taking a moment out of my night to send some positive thoughts your grandpa's way.
