Are there any numbers to call for English speaking people?
If as Jon357 says in the post above yours, that the UK Samaritans phone number works from Poland, then the number to call is ( +44 ) 116 123.
There is also a link through the Samaritans website to Befrienders Worldwide who have international centres and help people requiring emotional support. There is a centre in Poland if you click on the link to country, and a phone number is provided. Unfortunately, I really don't know if they will have anyone there who speaks English or not, but worth a try.

Hope you find someone to talk to.
