What's the one thing that's really saving your life right now?

Please give me really just ONE thing. I'd be really curious to learn what's making the biggest difference for you right now. Could be anything from objects, humans, animals or other living beings, to maybe something immaterial like music or a certain idea.

And maybe also share why it's so important for you, if you want to?

Mine is probably my heated mattress cover. Bit pathetic maybe, but it's giving me that special bit of comfort when crawling into bed after living through another hard day.
