Angel,
What you described happens to me ALL THE TIME! I can't believe you have the same thoughts. I can't stop picturing myself choking when I am eating. About a month ago, it was really bad - I couldn't eat solids. I'd even picture myself choking on liquids (which isn't even possible!)
The thoughts are very intense and once they come, its hard to continue eating. However, I can tell you that it gets better with time. The more positive eating experiences you have, the less these images will pop-up. I find that I am improving, but its definitely hard. I still can't stand eating alone, or eating 'tougher' foods like steak and pizza.
I'll post a seperate thread here about this soon. Much of my anxiety relates to my breathing and this particular problem has been a huge cause of my panic attacks.
We can beat this!
Brad
