Is this email written correctly

I am extremely sorry for my late reply. I got food poisoning and I was in a very bad condition. Still, I am not feeling very good. I am very sorry that I did not answer your message earlier. I received your lovely invitation card. Thank you for remembering me. I very much like the design of your card. I am very sorry that I could not come to your birthday party. I hope I can visit you in the US next year. Do you have any plan to visit Poland?
