Im the same way,i usually use breathing techniques to help me or listen to music.

Yep!!! My therapist is going to start doing exposure therapy with me to help.

I use EarPeace noise suppressing earplugs. They come with different filters that block different levels of noise, and I use them a lot when I'm out and about, overstimulated, or have a migraine

Yesssss i just figured it sensory processing sensitivity…. Loop ear buds

Hi, me and one of my friends have similar issues. We did some research and it sounded like misophonia... may be different for you obviously. This type of thing can link to a couple different "issues"

I literally can't stand the sound of people chewing at all it makes me feel very stressed and annoyed I try to eat at the same time as the person or listen to music

It could be overstimulation or misophonia; A strong reaction to specific sounds. It may cause a reaction to sounds such as dripping water, chewing, snapping gum or repetitive noises, such as pencil tapping. I suggest listening to music, meditating, removing yourself from the area, or asking the person to stop

Yes I deal with it all the time and have done my whole life. My mother has misophonia as well and we believe its due to sensory processing issues. I usually cope by watching something whilst near people eating or playing music when that's not possible. You could always ask people to eat with their mouth closed but many won't. These usually work pretty well but if not just walk away to save your sanity.

with chewing noises headphone obvs help, but as you have mentioned that if chewing starts to annoy me i tend to do my breathing exercises and then just try spot random things in the room? like a game i suppose it distracts away from it in a way. hope this helps

Same here, I can't stand chewing noises either! I will think of a song I like and play it in my head when around people who are making these noises that are strangers. If it is family or friends I tell them to please quit.
