Good job, Alexis.  Your writing needed only some very small changes.

Today in my job

Hi everyone! My day was troubled because I woke up late.  I went quickly to my job,  but I arrived on time. It's It was great! Then in my office I was waiting for millions of documents!  (Or maybe you mean "I had millions of documents waiting for me.")  I had a very busy day!! But I could control it.

Please correct me.
