I would die of sadness...

I'd be very sad because I lost a great friend.... u_u

I would feel really bad for like a long time...

That'd be pretty sad, yo! Yousa awesome girl(With full membership to the Guild of Messed up Minds=3). Especially with so with you being so young. No matter how hard life may seem right now, remember to live life by the best moments, because theres so much to experince in life! If you find yourself ill; make a bucket list and live what life you can to the fullest. If depression starts nagging; find things to bring happiness.
Our time here in this amazing world (and it IS an amazing world; from the manmade tech developing practically in our on hands, to the animal so diverse and amazing and the natual things only seeing really grasps it) is short, so all we can do is make it sweet and send ourselves riding into the beyond in our coffin sidewards going Weeee!

Bit of a tyrade there, I know, but Im just tring to spread positivity. (yet draws gory stuff? weirdXD)
Serioisly you just up n dieing would be sad for many reasons.

I would feel hollow for a long time knowing there isn't a thing I could do about it. Emotions disgust me, so I'm not getting into that.
