Phobia

Last night my husband's stomache was kinda upset. And I was really worried because I know once he is not feeling good or have stomache upset, he is going to pass out. I kept my eye on him, I didn't go to sleep even if its already almost 3am besides I couldn't sleep anyway. I told him that I'll call police if he will pass out but he didnt want me too. He just want wet wash rug on his forehead.
Im sure dont know what to do, coz last December he passed out coz his stomache was upset too. But im sure glad he didn't pass out last night. Im just having phobia. I dont wanna see him pass out anymore coz there is nobody here could help me. And he dont want me to call anybody.
