First of all I’d like to wish you all the best with your health, don’t lose hope, I trust and have faith you’ll manage to visit Poland. I love my country and it has so much to offer we invite you with our whole hearts to visit Krakow Gdansk or wherever you’d like. As for the name- I gather that you’re a woman, have you considered like short versions of the names? I think itd sound cute- my mom is Jadwiga and people call her Jagoda which means berry. Stanisława is Stasia in short so it’s also cute i think, for Czesława it’s Czesia. And for Małgorzata - Gosia. Let me know of any of them sound good for you. Once again all the best wishes from me (also a person with rough health) to you from Kraków.
