Translation - Pools-Italiaans - Oczywiście,że Cię pamiętam. U mnie wszystko...

Certo che mi ricordo di Te. Da me tutto va bene. Nel maggio avro' l'esame di maturita'. E Tu come stai? Vedo che ora sei in Grecia. Spero che vivi bene.

Meaning the same. Style better for sure. Thank you agnesepm. What should I do, Efylove? Should I change it all?

Polish phrase “A u ciebie?” literally means "What happens/What are you doing", or "What's up?",so I think "Come vai" is better here. “Come stai” means rather “How are you”. Don't you think?
Moreover, „U mnie wszystko dobrze choć…”. Agnesepm has forgotten about the word „choć” which I had translated “benché”…
