What is your opinion on this poem? How can it be improved?

So I am a 15 year old girl who’s struggled with compulsive lying for quite a while now. I’ve destroyed so many of my relationships, including my relationship with my best friend/crush, and mother, to name a few.
I wrote this particular poem after an angry fight with my mother where she told me I need to stop lying (very true) and that my lies aren’t really convincing and that every time I lie I cause a piece of my truth to die, and that the truth can only be very thinly veiled by lies. I used these concepts in the poem. I’ve had an interest in poetry for a long while now and I just wanted an opinion on my poem. Please keep in mind that I’m a teenager and a rather dramatic one at that :).

Nails in your tongue
blood on your lips, the words fall.
I sacrifice you.
A siren by birth, impaled on
your contralto whisper.
The devil calls for their surrender
to the staccato halt of
the cutting truths underneath the sound of
your convincing lies.

So I used the concept of a siren because my compulsive lying feels like as much of an affliction as a siren’s voice. I’m afraid to talk to people, as I imagine a siren would be, because I don’t trust myself to tell the truth (also I’m obsessed with singing and sirens are so cool. I mean, they kill by singing! :)). Moreover, I’m causing the “death” of my truth with my lies. The word contralto I used because it is the deepest, darkest, richest female voice and I felt that was fitting with the concept of a lie (and I did not intend it this way but coincidentally I’m a contralto too so even better!). Oh, also I’m addressing myself in the poem.

Anyhow, I want to know if this poem does anything for you, like if you catch its vibe, and also, technically speaking, how can it be improved?
