I can certainly appreciate what you're going through.
My Grandma died of Cancer. She was the nicest lady in the whole world (well, to me, anyway) who gave everything for her family and friends and asked for nothing in return, and I remember how hard it was for my Mom to see such a sweet women being forced to suffer through so much pain.
You may think you need to do something extravagant, but really, all you need to do is let your Mom know how much you love her, and just be there for her. Most importantly, give her lots of hugs. They say when you hug someone, you share some of your energy with them. My Grandma was supposed to die quickly according to the doctor because her Cancer was that bad, but she miraculously lived several months past her expected death date. The doctor couldn't say why, but if there's any truth to that theory, then all the love we were giving our grandma is possibly what kept her going as long as she did. You're Moms a lot younger then she was, so she'd definitely got that going for her. As long as you can keep your mother motivated and staying positive, miracles can happen. Or at the very least, you can make the transition from life and death as painless for her as possible, considering the circumstances.
Also, she may feel like a burden if she knows she's making everyone so sad, so just in case that's true in her situation, make sure to let her know that she has nothing to feel bad about, all she should be focusing on is staying motivated. It's okay to cry, but you also need to be strong for her to show her that you'll be okay.
Also, just remember, nobodies perfect, as long as you're making a conscious effort to be there for her, then you're giving her the best gift you can.

Her health is deterroriating fast. Her cancer is spreading.
The doctors now say she has anywhere between days and weeks.
How to prepare death when its coming like a speeding bullet.
There is just so much different things running inside of me... Anger, guilt, sad, denial, ....
Aw, I'm really sorry to hear that. Don't worry about being any one way though, as this really isn't something you can easily prepare for. Just go with what you feel and work through everything one day at a time. There's no easy fix, you just have to keep your chin up and keep working through it. At this point I guess the best thing you could do for yourself is expect the worst but hope for the best. That way, you've got all your bases covered, and hopefully you'll be able to deal with whatever happens. Best of luck to you and your family, and here's hoping your mother manages to pull through. I've seen it happen before, so it certainly wouldn't surprise me.
