In America, if someone says, "I'm feeling sick", I would reply, "sorry to hear that". Sometimes, "I'm sorry". I know it's an American thing to say 'sorry' for things like that. What expressions of sympathy can I use in Polish? If you don't do that sort of thing, what do you say?
Examples (if context matters):
I'm feeling sick
I worked very long hours
I couldn't sleep last night
My stomach hurts
I had a fight with my girlfriend
Is there an expression that covers all of these?
