'Dea'r' DEAR Maciek
I've just got your e-mail, and I was VERY sorry to hear THAT you're worried
about your loneliness.
The best thing to do 'if' (niepotr) is TO find A friend, 'when were you empathy' (nie - nie rozumiem tego .....-
To talk with your class - to zdanie potrzebuje cos jeszcze....
Someone WILL hear YOU with certainTy.
You ask to Cinema or to 'Theather' TEATRE - ale kogo?.
You must 'to' (Niepotr) spend very LONG time with your friend.
You should open yourself 'on you around people' (to people nearby?).
You could also buy A beautiful dog.
'The' A dog is the best friend FOR A MAN (human- raczej tak nie uzywamy).
With certainTy YOU WILL get to know A person, when THEY 'been yor'? ARE friendly.
