Feeling super lonesome right now

Oh man, so I just got the news that my mom's really sick, and she's been keeping it under wrapps for a while now. She definitely didn't want anyone to worry, but here I am, totally blindsided. And to make things even more intense, no one else is around to help me through this. I'm struggling to figure out how to handle everything-it feels like a ton of bricks just dropped on my head.
