Andrea, your English is at least as good as the average of what we see in this forum, and much better than what we see from a large element among our younger, perhaps intelligent, but not-so-literate native speakers. When the TV generation took over as public school teachers, being not so good themselves at grammar and spelling, the literacy standard among our young people began a downward drift which may never be turned around. They seem to understand each other though, so maybe it's just me.
