Overflow
When Sakura receives another memory, they flood into her mind like a tidal wave of pictures. Sometimes afterwards she gets horrible migraines which she hides unbelievably well from the others. She feels as if her head will burst open, revealing all of the information inside to everyone. But never has it before, and she doubts it ever will, because the memories are proportioned as such to make it just enough for her mind to endure.
But sometimes she wonders. What if she receives too many memories at once? Would the pain be so excruciating that she couldn't think? Would she die? Or…would her memories simply overflow from her mind, spilling helplessly onto the dirt road?
She wonders what it's like to have your memories overflow out of you. She wonders how they would go (though she's fairly sure it would be out her ears) and what they would do once they were out. She does not realize that she, somewhere in the deep chaotic depths of her wounded mind, remembers what it's like. What it's like to have your memories – your heart – your soul –flow right out of you.
Somewhere deep inside, she remembers that excruciating pain that makes you want to claw your eyes out. So she continues to fool herself, thinking about her returned memories and that odd physical pain, and hides it well as always, kissing her own wounds, recovering on her own – after all, Syaoran-kun and the others do enough for her, how can she ask more of them?
She's a big girl, she's sure she can take care of herself.
