What do these lyrics mean?

It means the songwriter could use a visit with a mental health professional and a script for an SSRI…

Actually, it doesn’t mean anything.It’s better to just dismiss it as meaningless.

It’s ecstasy in lyric form – overly sexual and chemically inspired dependence. Typical teenager rave party crap.

The writer has gone for the fake, cliched, melancholy vibe in the mistaken belief that, by default alone, this makes for a great song with deep meaning.
It doesn’t, more like desperate, formularic, attention seeking crap.

I like it. It’s about the desperate need for the writer to connect with the subject of his affections.
He wants to cry with her, not laugh. You can laugh with anyone, but if you share their pain, you connect with them.

@gorillapaws No good writing her a prescription if she’s just going to wash her hair with it.

My interpretation is that she’s hooked on codependence—

It’s really not deep at all, nor hard to interpret. She is obsessed with a crush and lovesick, and it’s a cry for help and this love interest is the only one capable of saving her.

You want some good stuff, go listen to the album A Momentary Lapse of Reason by Pink Floyd.

Sounds adolescent to me.
