What even is this bullshit

So remember my aunt with the severe burns and the broken ankle full of pins and plates?

I got an e-mail from my mom yesterday that just said she

has blood clots in her lungs. She is now at st. Mary's hospital. Depending how fast the clots dissolve as to when she gets to come home.

This is the whole e-mail. So it's left me with more questions than answers, starting of course with What?! Fucking WHAT?!

I mean, I guess if it's "when they dissolve she comes home" that means they will and she will. Mom doesn't seem worried at least. And...I guess it's a break for her and her sister who had been having to alternate spending a few days at a time with my grandma and this aunt, both of whom now need looking after; hopefully she'll get better care for the things already wrong with her if she's in a hospital (though if she's at St. Mary's (in Rochester) she's a long way from the specialist burn unit she had been visiting (in the Cities)!).

But...blood clots in your lungs sounds really bad? Why has this happened?! Are there any other complications from whatever's caused them, or likely to be?

And most of all Jesus when can my family and particularly my aunt catch a fucking break?!
