She's dying, and she knows it.
There's a reason why she doesn't have any thought bubbles in the last chapter. It's cause it would reveal that she is the only one who needs to know when she'll die and her condition.
She doesn't want her friends to worry again and she wants to fill her bucket list.
You can't change your fate. That's what the story implied.

SPOILERS
I'm happy it was a happy ending, but I don't get why her heart started beating again? The power of love? Also does she have to keep taking the medicine forever or is she done? (in which case does the friend mass-produce it lol) and the last panel means her head keeps coming off or is it just a scar?
If someone who's not dumb like me gets it, please explain lol
Also, I love Rio!
