Is my people eating food phobia normal?

Ok so, I've had this problem for as long as I can remember, but as I've gotten older its gotten so much worse. Its not the noise people make when they eat, that actually dosent bother me, my main problem is the way people eat. I cant stand when people talk with their mouth full It's absolutely vile, it makes me want to vomit and if someone does it I start internally heaving and have to excuse myself to go to the "bathroom". I used to go to college with this girl (luckily she dropped out) who used to order really gross food like a toasted sandwich with tuna and mayonnaise and would yap away the entire time she was eating and would open her mouth really wide to laugh (she had gross teeth too, so that didnt help) and I literally had to stop eating lunch with my friend group because I lost my appetite everytime! Another thing I cant stand is when people get food on their face, I know its so bad and people cant help it, but it just grosses me out so bad, the worst for me is with little kids, I know they cant help it, most kids are naturally messy eaters but I cant look at them if their face is covered in food! The worst thing about my problem is when other people prepare my food. I have been to several friends houses where I couldnt eat anything as I didnt know where the persons hands had been! I think that part of the phobia started when I was a kid in my friends house and my mums friend was making us a salad. She had really gross hands, with nails bitten down as far as they would go and kept wiping her nose with her sleeve as she peeled hard boiled eggs. Luckily I have managed to mostly overcome the phobia of other people cooking as I really really dont want to be rude in other peoples houses, it only happens when the person has really gross hands, long nails ect! Anyway, back to how other people eat, even the tiny things can set me off, all it takes is for someone to start licking their fingers and I have to go, I cant deal, I really really despise finger licking, its not just the germs, its the fact that someones salvia and half eaten food is now all over their hands. Anyway, I probably sound like a horrible, fussy and judgemental person but I really wish I didnt feel like this! It would be nice to know that I'm not alone
