I’m so scared (TW not censored)

So I’ve been doing so much better with my emetophobia, haven’t come on the subreddit. Eating through anxiety nausea. Just generally these last two years have been doing great, even dealt with COVID 2 months ago that led me to aggressively dry heave lol.

Then yesterday I was at my boyfriend’s house, mind you I’ve been sick this week with a cough, stuffy nose, sore throat, and body aches but have been feeling better. He and i were watching a movie last night and he said his stomach was upset but he thought he was Nic sick from his Zyn and started feeling better.

Fast forward to 2:30 am i wake up to him standing in our bedroom doorway and saying babe I’m so sorry i just threw up a lot in the bathroom I’m not sure what’s going on but i feel terrible. I literally almost passed out lol i had cold sweats shaking pinhole vision. Once i calmed down I packed up my things and went out to talk to him. He said he was having HORRIBLE body aches like worse than he’s ever had and i felt his forehead and he was very hot. He told me i should leave because he knows how bad my anxiety is. So i went to my uncles. Around 6 am i went back to his house and brought over some soup and pedialyte and liquid IV. He was sleeping and woke up briefly when i got there. I left again and when i came home immediately showered and threw my clothes in the wash and sanitized my phone and stuff.

He’s been texting me saying he hasn’t thrown up since but has been having watery diarrhea and still horrible body aches and fever and severe exhaustion.

I’m so so beyond scared. We spent the entire weekend together (Friday, Saturday, Sunday) and had sex yesterday afternoon. I haven’t eaten and have barely slept. I haven’t regressed with my phobia this bad in like two years. I’m not sure what to do :(. I feel like a bad partner but i also am terrrified to catch what he has.
