Loud chewing

I think I chew loudly and I hate it. I'm not sure if its my anxiety making me think I do or whether I actually do. Because everywhere you look people are complaining about it and say how much they hate people who chew loudly. But my boyfriend has made fun of me for it at times and I'm now really self conscious.

Apart from I don't know how?! I never open my mouth while eating as I find that so disgusting. But I don't know how to chew quieter. Sometimes when I'm super aware of it I end up chewing stupidly slowly at work trying to make as little noise but it's harder than it sounds!

I dunno just hoping I'm not the only one? It's so annoying tho as I find it hard to eat around people as I worry too much.
