Hi!
In (at - nie wiem co powinno być In czy At) the begining of my letter I want to greeting You.
I'm really sorry that I haven't send You a photos (photographs) for such a long time but I was busy.
I think the photographs You like it.
I am interested what You are doing, how is Your New School - Police ( albo nie wiem która forma Police - School ??).
I hope You are happy and everything is fine, and I'm sure You manage with that. - (chodzi mi tu o to iż sądzę że sobie w tej szkole poradzi - ale co do tego zdania nie jestem pewna).
At the finish I would like You to invite to Poland - who knows, maybe
someday You visit my country.
I wish You all the best, take care.
Greeting for You and Your family.
Remembering ( pamiętająca ??) about You ...
Ps.: You are still in (czy on??) my heart
I'm waiting for your answer

AT the begining of my letter I want to 'greeting' GREET 'You' (you mala litera).
I'm really sorry that I haven't 'send' (zle czas - tutaj SENT) 'You' (you mala litera) 'a' (niepotr) THE photos for such a long time but I was VERY busy.
...I think the photographs You like it. ...(to nie jest gram. I think that you will like...),
I am interested IN what you are doing, how is your Police - School?.
I hope you are happy and everything is fine, and I'm sure you ARE managING
with that.
At the 'finish' END I would like 'You to invite' (nie, nie - TO INVITE YOU) to Poland - who knows, maybe someday you WILL visit my country.
I wish you all the best, take care.
GreetingS for you and your family.
'Remembering' (Fondly remembering...)
Ps.: You are 'still' (moze lepiej 'always') IN my heart
