dance with me at the end of time (слэш)

He goes back to the Gryffindor dorms with a vial — one of his own, he wouldn’t dare to touch Snape’s vials, wouldn’t dare to steal from him — full of a transparent liquid, much like water. This would do the trick, this would end the pain he’s feeling.
He’s going to drink it before going to sleep. But… something. He doesn’t, halts just as the vial is inches away from his mouth.
He rips a piece of paper from one of his notebooks, writing down:
-Your name is Harry Potter.
-You were born on July 31st, 1980.
-Your parents, Lily and James Potter, died when you were a baby, so you won’t meet them.
-You’re a wizard.
There are many other things he doesn’t want to burn inside his head when he drinks the potion, but he doesn’t write them. These are enough.
He drinks the potion.
