So sorry about your news, Tokin. I think Granny gives good advice. She's exactly right that that aneurysm hasn't appeared overnight. It's been there a while, probably all your life. And if it were likely to be life-threatening, they'd have you in the hospital now, sedated.

I've had neurosurgery to fix a venous malformation. It's a lot easier than you might think, actually. Once it's over, you can join the club by saying, "I swear, I'd rather have brain surgery than do ________," and you'll know exactly what you're talking about!
