Help needed with imagery

[pine monolith]

Teacher tasked us to write a simple villanelle that doesnt necessarily need strict rhythm, but needs to have good imagery about an emotion pre-chosen. Would be great if someone could suggest something to change or add for better imagery, also critique would be helpful.
Villanelle:
I don't know what i want, but it's not this.
Time is all spent.
Wasted times vanish in a glimpse.

Everything is now in small bits.
Fragments from then.
I don't know what i want, but it's not this.

Times i used to reminisce.
Everything has went.
Wasted times vanish in a glimpse.

Nothing matches, it all conflicts.
It wasn't like this, but now it's the present.
I don't know what i want, but it's not this.

All i see is an eclipse.
Forgotten the antidepressants.
Wasted times vanish in a glimpse.

Hollow like addicts.
This feels pleasant.
I don't know what i want, but it's not this.
Wasted times vanish in a glimpse.

Instead of “hollow like addicts,” you might say something like “hollow as a forgotten song.”

Instead of just saying “everything has went,” you might say “everything has slipped like sand through fingers.”

“Nothing matches, it all conflicts,” you might use something like “Colors bleed together, a canvas of confusion,”

instead of “pleasant,” consider “syrupy” or “bitterly sweet,”

"All I see is an eclipse."

Suggestion: "All I see is a shadow's embrace, eclipsing the light."

"Hollow like addicts."

Suggestion: "Hollow as a forgotten song, echoing in the void."
