Food Anxiety

I honestly don't understand why I have to panic over everything I eat or everything my husband eats. Just because I have a food allergy to one thing shouldn't rule my whole life....should it?? I am just so terrified about every single piece of food or drop of drink that goes into my mouth. The worst part is that my poor husband can't eat anything and kiss me without me freaking out and thinking I'm going to go into anaphylaxis. My husband gets so upset at me. He thinks that I can just turn it off. I truly wish that he knew what it was like for me to go through this every second of every day fear. I wish he could understand. As I write this I am at hour 4 of a panic attack because he drank some Acai Berry juice and then kissed me. I've never had acai berries, I don't know if I am allergic. Of course, I went into panic mode, like always. I started to panic, I got short of breath, then I got really sweaty, then I felt like my lips were going to itch off, then I I feel my throat and chest tightening. But I know all this is in my head because I can still breathe, my lips aren't swelling even though they feel like it, and I am still at myself. HOWEVER, this panic has been going on for 4 hours and I can't convince my brain to just STOP PANICKING! If i were going to go into anaphylaxis, it would've already happened by now and I wouldn't be sitting here typing this.This is just one event but this happens almost every single day. WHY WON'T IT STOP???
