It resonates in you those words. You never really knew what was a home. When you were at your house with your family you wanted to go home somehow.
Home is a concept you feel you haven't really experienced in a proper way. Home is happiness, confort, feeling like you're loved and you belong, being content in your own skin for once. Or you imagine it's that. When you "want to go home" you want to feel those things instead of feeling like a failure, like your friends don't see you as one, like you want to cry for no reason.
Screaming would be more useful probably. Hiding never resolved this feeling but putting yourself out there and waiting but seeing nobody come confort you in the idea nobody enjoys your presence, that everyone pretend with you.

Your best friend is your sister. You have friends that you can count on a single hand and you feel as if even if you lost most finger you could still count them.
Being the number one to someone might help but you're too weird, too fake. So you spiral, nobody wants you, you're just convenient, nobody wants you, nobody loves you, you're a failurefailurefailurefailurefailurefailure...Have you ever been loved for you ? You don't think so...
You wanna go home...
