Hey it's me again, 18 y/o with a huge fear of throwing up and a long history of anxiety. My friends is staying over as she normally does after we hang out and we usually sleep in my bed. Tonight she woke up and went to the bathroom around 3am , we went to bed at 2 and around 1230/1 she ate a meal. She woke up from sleeping on her stomach with a bad stomach pain. I woke up as well and noticed and I am on alert because her stomach hurt at first I thought she was sick because she spent a bit in there but she said her stomach hurt so bad but was better after going to the bathroom and she's fine now. I know I'm probably thinking way too much but I can't help it, how can I protect myself from getting sick if she is sick? Can I even do so? Especially since she's in my bed? I can't help but be paranoid
