first off - I am completely new to this forum, so sorry if I posted this into the wrong place!
I am a 27 year old German woman working on her masters degree, however now I am demanded to write a paper in LaTeX, with which I have never worked before. I figured out some basics and kind of get some things to work. But unfortunately, I am slowly running out of time on the paper and it doesn‘t look and work as it should and I am stuck here, because nothing I read or search seems to work, especially with citations, but generally all over the document, things are not as they should be.
I need help!

Can anybody spare some time for me and help me figure some stuff out that should be kind of on a beginner to slightly advanced level?
Thank you so much..!
Best
Lena
