I agree with you it's horseshit. What you're saying sincerely makes total sense to me. Has to feel terrible. I would feel detached from my work as well, I think.
You're experiencing alienation from the fruits of your labor. Your labor being exploited to maximize profit. Unfortunately, the comments here are right. It "makes sense" in the sense these experiences are characteristic of life within capitalism as a laborer.
Functionally, your location is being "colonized," so to speak, by capital. I don't know if there's a real phrase for it, but I suppose it could be described as "telecolonization." Management has found a resource (your labor) that can be cheaply extracted by alienating you, the "telecolonized," from the value your labor creates.
It is bullshit. If you want solutions, your recourse is either collective action/unionization or finding a new job. You're being exploited by capital more than your coworkers. That is the context from which this sense of unfairness arises, I believe.
