->I would like to ask you...
->I have to tell you that last few weeks...
->"In the beginning I want to back to my home, but later everything change" - to zdanie jest niepoprawnie napisane, powinno być -> At first I wanted to get back home badly, but later everything that changed.
->I've met...
->to go back home...
->has ended zamiast has finished
->"but I want to stay" -> powinno byc: and I wanted to stay...
->Finally I've come back home...
->"I want to stimulate you to care your body and your health" - bez sensu, zamiast tego -> I want to encourage you to care of about body and your health.
->"I`m greeting you" - nie pisze się tak na końcu listu, poza tym chyba nawet jest źle napisane :-D
