Post-fight pettiness in a serious situation

Fiancé and I had a fight the other day and I’ve been giving him space. He’s not mad at me even, just upset with the situation regarding his immigration status right now. Problem is, I’m literally in the middle of a serious pleurisy issue right now. I can’t breathe without severe sharp pain in my chest, this is common but it’s never lasted this long before. I can’t go to a hospital because I’m visiting him and obviously I have no insurance in this country. At this point he’s acting like he thinks I’m faking for attention, he’s just sitting playing a game on his phone. He doesn’t even give a shit, meanwhile I can’t fucking breathe and I’m in extreme pain. What the actual fuck is this???
