you always keep passing me by

i've never felt so alone. i don't know why i feel this way, but i do. a house full of people, full of people i've know almost my entire life yet, it felt like i didn't. like i didn't know them at all. i was a stranger, they were strangers. i've lost everyone who once meant everything. i've been replaced by every best friend i had, and only i'm to blame. i wish they knew how much it hurts, to feel so excluded. i miss them, i miss my friends. what happened?
