A bit of background. While i work in a company that's not IT based in any way, i'm a web developer for the company's main system, patching bugs and adding new features whenever asked. This is my first job, and i've been here for almost 1 and a half year.
While at the start i was pretty stoked, i'm feeling a bit underwhelmed now, because most of the requests that gets to me via my manager(only me and my manager covers the IT area of the company, but my main focus is developing the system) end up not being used after going through the stress of making it, via pressure from my manager and from the area that requested it(Example being a feature requested by HR, having multiple meetings and short time period to make it, for it to be ignored for 5+ months)
So now i feel like most of my work goes nowhere, i feel undervalued, burnout(even after vacations), and i don't have much space to grow on my carreer on my current company, since it's not IT focused.
Also, i'm having some communication issues with my manager, i feel like he's ignoring certain things that i say to him(Example, we agreed on something for a week, then mid-week he says that want that thing done by the end of the day)
I'm afraid to quit my job to find a new one, since i'm currently paying/going to colleage and have to pay other expenses of mine. Not because i don't want it, it certainly has crossed my mind multiple times.
I might add that i live in Brazil, if it changes anything.
Edit: My question is, how should i approach my manager about those issues, since he's a bit stubborn/aggressive about his opinions and i fear that we will be on bad terms from now on.
