Started to eat some soup but it tasted like metal!!?

please help me, i am freaking out. first i just want to say that i have extreme anxiety and i freak out over things very easily. i was ok all day, no metal taste in my mouth. i've been on a diet for 5 weeks and 1 day. tonight for dinner i planned on having hearty tomato soup with pasta in it, the Chunky brand. i poured it in the pan and took a bite of it, it's usually DELICIOUS, but it tasted like metal really bad. so i got a different spoon and tried it again, it still tasted like metal. it was horrible, i was spitting and drinking everything i have to get the taste out. so instead i had a lean cuisine, tasted great until the very end i started tasting metal again. and now, 30 minutes later, my mouth tastes like metal still. even water tastes that way. could something be wrong with me or do you think it's from the soup? my husband ate the soup, he said he couldn't taste any metal. so that kinda worried me. i'm scared i'm going to go into anaphylactic shock or something, even though i know it happens rapidly..i have irrational fears. please don't post anything mean, it might seem silly to some of you but this is a real fear i have right now.
