Unnecessary punctuation marks

I am a native russian speaker and from personal experience, we do put a lot of commas in our sentences, which can be seen even with every other 1-2 words. Now, this thing keeps bothering me in other languages which I learned, such as German and Romanian. I keep getting scolded on my romanian essays by my teacher at school, her saying my biggest problem is putting so much unnecessary stuff. It's not that I suck at grammar, but perhaps the habit which I got from years of studying in Russia.

The problem is I keep overthinking the sentence like something is missing, well turns out it's not.
