I used to do the same thing. I think the best way to get out of that cycle is to start trying to cook something good just 1 day per week. The rest of the week can be trash, but just plan 1 good recipe.
In the beginning, making a new dish takes forever and feels really stressful because it's all unfamiliar, but if you do it enough, it becomes something you can do on autopilot with very little thought or planning. Even having just 2 or 3 autopilot recipes that you've perfected logged in your brain somewhere makes such a huge difference. That doesn't mean you have to cook them every night, but you can at least break up the monotony and unhealthiness of your current meal options.
Plus, at least for me, having a meal that is healthy and actually tastes really good makes me so much more productive when I get back to work.
