my brother is always eating and my house is loud af

Whenever I go into the kitchen, my little brother is always eating. I only ever really come out of my bedroom to go to the bathroom or to get a cup of tea/some food and whenever I go into the kitchen to make said cups of tea, this little stuffed turkey is always eating something. He literally just had dinner 2 seconds ago and is now feasting on an ice cream sandwich. And he’s always eating crisps.

This is annoying to me because I have deadass HORRIFIC misophonia, which basically means that I get extremely annoyed/have fight or flight reactions to certain noises. The problem is, I have an issue with almost every noise on the planet, and I have a reputation for hating the noise of people eating/sniffing especially, and my little brother is doing that constantly. It is somewhat tolerable because the sound of the kettle and the loud ass videos he watches covers it up, but it’s still annoying. Also who even eats that much in a day? (I don’t know why I’m talking knowing I’m a little fatty with a whole box of lucky charms next to me but I just got my first boy period in months so I get a pass) 

talking about my misophonia I also have an issue with sneezing/coughing too much, people coughing up phlegm or whatever, walking too loud, the vibration of a cis man’s voice, heavy breathing, laughing (only when I’m already annoyed/overstimulated) and smaller things like…pencils writing on paper or keyboards clicking, but those only really annoy me when I’m annoyed in a test. Imagine being around me. I am the most SPECIFIC person on Earth. To be fair I can tolerate these sounds if it comes from my friends or someone i like/trust but most of the time I have headphones/earphones off because I am so incompatible with people’s noise. do not eat the ice cream sandwich around me. bad things shall happen.
