She can't take it anymore

Again the sleepless nights begin,
Overthinking creeps in again.
Loving hurts every time,
Everything gets tough to climb.

All the butterflies are dead in the stomach,
Coming out now through the vomit.
Daylight’s getting dimmer,
Nightlife feels a little calmer.

The story's getting hard to end,
Like I can't swallow, can't even bend.
The ceiling's falling on my head,
Earth spinning faster than it ever did.

Everything's blurry to the core,
She can't take it anymore.
