scaring my fiancé

About a year ago I was sexually assaulted, and the anniversary is coming up soon and my fiancé has had to work 7 day weeks for the last 1.5 months. Because if this I have barely eaten anything in the past 1.5 months. I'm lucky if I am able to eat one meal a day. He's scared of loosing me because I have already had one episode when I passed out and he couldn't get me to wake up. What do I do? And please don't say just go and eat something, it's not that simple.
