<human>: Give me the gist of the text in a nutshell

So I knew going into this that the labor was going to be intense. And while I certainly don't prefer the aching, soreness, and stiffness, I accept them. What's really hard is developing the mental fortitude needed to be able to take the barked orders, micromanaging, and the fact that I'm at the very bottom of the totem pole with basically no way to defend myself should I make an honest mistake. I don't think my boss is the shady type like some of the ones I've had, but there are definitely dollar signs in his eyes 24/7, and his addiction to making sales causes us to work ample overtime. Today some sweat mixed most indubitably in with some tire ruboff managed to sink into my right eye. I was in instant stinging pain, and when I got to the bathroom, the pain left me barely enough time to splash some much needed water in. I looked at myself in the mirror, I was red, marred by tire ruboff in my face, and my right eye looked like I had just undergone an allergic reaction. My pupils were also small as hell, indicating they were feebly attempting to take everything in at once, rather than being able to focus one thing at a time. I heard a voice in my head telling me for the love of God to stop punishing myself like this. The thing is, I need the money, and in order to move on with my life sooner rather than later and hopefully in less misery, I will have to continue this. Winter is coming, meaning some days will last as long as into 1 o clock into the morning giving our area's demand for snow tires according to veterans of the store. I am not sure how well I will be able to handle that, especially if they say I need to come in at 7 in the morning hopefully to earn one 30 minute lunch break somewhere down the line. Anyway, advice? (and I don't need you to say I'll have to cut corners and tell white lies in order to survive; my superiors have already made the necessity of that quite clear xD).
<bot>: This job is hella difficult and the busy season of the Tire sector of the automotive industry is upon us, HELP!
