Hi Maribel, I put the corrections needed in bold so that you can visualize them better. Please tell me if any of them change the original meaning, OK?

Hi, I received this, don't quite understand what I should or if I should do something.
I am going through a very busy time, so if this does not concern me, could you please be so kind to reply?, then I could move forward.

I wonder if that "if this does not concern me" could be:
"if that's no concern of mine" (if that has nothing to do with me)(if that's none of my business)

What do you think?

Thank you both! Now it makes sense.

Thanks for the corrections, I edited and it looks much better.

(But if I did it again I think I would use small letters all the way because it is like a chat message and the original has flaws in punctuation and in putting different kinds of clauses together just like that...also we should use capitals in "Hei..." and "Tässä..." but they are deliberately omitted; for convenience I've seen the english to do it, too.)

would be:
",so if this doesn't concern me.."
or
",so if this isn't any concern of mine.."
or even
",so if this ain't any concern of mine.."

Oops, there was something wrong with my editing, sorry. A new try!
