How Do I Quit Crying?

so, my kitty blackfoot died a little while ago, two weeks, to be exact. i still feel empty and lost and just so sad.
she was my best friend, my protector, my confidant, and so much more than what i keep being told she was.
calling her a pet doesn't even begin to cover it. she was more than family.
you see, she found me 2 weeks before my 8th birthday. she walked into my family courtyard and has never left. the first thing we did when she found us was give her warmed cream (just a little, we didn't want her to be sick) and some salmon.
i grew up with a kinda crazy mom, but who didn't? every time she would yell or scream or hit me, there came blackfoot like a bullet out of nowhere, meowing and (gently) biting my mom till she stopped.
i told her all my secrets, and she was always there, curled up in my lap while i was sad or sick.
after my back surgery, she was my constant companion, doing her best to help me get better.
since she's been gone, i haven't really cared about anything.
i feel like a part of me that i didn't realize i had died with her. one of the best parts of me.
will i ever hurt any less? does it ever stop hurting?
i guess i'm looking for reassurance that someone else knows how i feel, and that someday, i'll just be happy i knew her, and remember the good times and be happy that i might be with her again someday.
i feel so foolish that i still cry myself to sleep almost every night, that i hurt thinking about her and the fact that she is gone.
so, i guess to end my ramble, any advice? any help?
thank you all.
