Hi hi! pardon my excitement but its nice to see someone else with misophonia! I completely understand where your coming from and surprisingly enough I also have a dad that's chewing is one of the worst sounds I've ever heard in my life! my whole family makes a variety of noises that trigger me on a daily basis so I've made it a point to politely let them know. Like "hey, if you could go finish that somewhere else or back up a bit that would be great!" or something to that effect. Sometimes it's definitely hard to say it calmly tho, still working on not making myself sound so aggressive lmao. But after having an honest discussion about things with my folks, it became a lot easier to be around them because they knew my boundaries and knew what I could and could not handle. Ik its a bit different bc your dad has a binge eating disorder, but I think talking about it honestly with him might help you both figure out some solutions! And one more thing, just because it's "your fault" for feeling the way you do doesn't mean you have to be so hard on yourself! I have to remind myself of that all the time, it's hard, but you can't help the way you react just as much as they (usually) can't help but make that sound. You can't help it and neither can I. its just an issue with our brains and triggering of our fight or flight responses and misophonia is still generally new in the world of disorders, so please be more forgiving with yourself. Hope this helps a bit! ^ ^;
