Two songs came to mind as I listened to this.

The droning guitar part you use reminded me of James Bay's "Let It Go". Your song is scarier. Alarm bells went off in me when you say "I don't feel like crying but I want to stop trying". It's the calmness that unnerved me.

That leads to the second song I thought of. It's a Lithuanian one called "Rami" or "Calm" that's sung by two women (who are identical twins in life) and one girl, each representing a part of the same person. The song is a inner conversation between the inner child and the inner mother of that same child. It sounds complex, but it works. The inner mother says to the child, "when the sea is calm and you want to scream... Make waves! Do something! I can't stand it when you stay calm".

I feel this inner conflict in your song. You're dealing with a breakup, but you're also losing your will to go on living, and you say you're wishing for the strength to stop trying, and your first line echoes in my head, "I still don't feel like crying" sounding like a muffled explosion ripping through your body but never breaking the skin.

In your very first line, you say that your pursuits are fruitless. Your personal value depends on attaining those pursuits. Immediately a question appears and hangs in the ether - Why?

That's was long-winded. Point is that there's a lot here that has worth. You let it out of its cage. What now?

Loved how the guitar melody shifts into place between the vocals. The shift in tone from general disenfranchisement (?) to an unravelling personal relationship is wonderfully subtle; the overall style is heartfelt and on-point.
The Prelinger video is an unexpected cherry on the cake.

I'm glad you posted this! Guitar works so well alongside the lyrics and your vocal delivery. I like how it kind of lifts up in the chorus too then glides back into the melancholy progression.

I felt this, and your vocal delivery made me tear up. Just feels so raw and real.

Favorite line was "I'm seeing my brightest days getting darker." It's interesting that that line precedes the only line that uses "we" and "our" instead of "I." As for the lyrical content, I know the feeling.
