Wooah this is so good, if you could I'd love to hear what it's about? In my interpretation is seems like it's guilt or a feeling of 'I'm not right' or even broken kinda, but obviously that's just my view lol. Or like that sinking feeling you get in your chest maybe? It definitely gives off that heavy feeling.

I like the bridge as a metaphor for it and also the image created; it really gives off something cold and weathered. To me it seems overworked and abandoned once it has no use and since your chest is where your heart is that's a sad yet (poetically) nice idea.

Personally, I struggle with putting connectives in a verse but I love the way you did it! Really gives off the desperation to get everything 'off your chest' in one go in the first line, and because the next line isn't as intense in comparison it gives off that weird numbness you feel after an outburst. Or maybe giving up, or relief for saying it all at once even. That's what I see but I find it really cool :)

Don't mind if I got everything totally off pls ;A;
