Does your bf know you're emet or suffer from anxiety? I'm the same way when I don't feel well or have an anxiety attack and for the most part I've hidden most of it from my boyfriend the 5 years we've been together (which was a challenge when we moved in together a few years ago!). My point is, he might be more understanding than you think. Maybe even helpful. I had to come clean with my bf when I had horrible food poisoning a few weeks ago and aside from not understanding why I didn't want to eat for a full day, he basically was very helpful It actually made me feel better that he was there.

chin up, I think you'll be ok!
