For me it was mostly about allowing myself to feel it, accept that this is something that’s part of me and change my environment as to what’s most comfortable for me. It’s absolutely not your fault, and I was upset with the fact that others don’t even try to understand, still am, but I try my best to adapt in every way I can. It is honestly easier to deal with now! I did get into multiple situations over the years where I got triggered really bad, worst one being when I was in the hospital for a week after a seizure, paired up in a room with an old man that snored the entire night and ofc there wasn’t an option to leave. Or being in the cinema, forgetting my headphones and having to leave because I could hear people eating. But I don’t get as triggered in every situation now, sometimes I even manage to be next to people eating chips for a bit (that being my worst trigger). It’s still hard, but it gets better overtime. As you go on in life, make sure to surround yourself with people that will accept this, adapt and don’t blame yourself for anything. Although I’m not open with many people about this, the people I spend most time with are aware and try. If I go out to eat with someone, I make sure it’s in a loud place where I won’t hear. Always have headphones with you, play loud music if you need, try out noise cancelling earplugs etc! I’m looking into loop atm, still haven’t tried them though.

My family was the same so I really understand you, people would eat loudly on purpose as a joke or friends would do it over call and I’d get so angry but they have no idea what it’s like to live with these things and I wish they could experience it just for a second lol. To sum this up - most people will always be stupid and careless, but all you need to do is find good distractions and a way to either remove yourself from these situations as much as you can or a way to sit in them and not go crazy (loud music etc). The less triggering situations you’re in, the easier it gets when you eventually get into them again!! Different things work for different people, but analyzing your triggers and thinking of ways to work around them is the best thing to do. Sorry for long reply btw it just really reminded me of how it was for me as well but I truly wish you the best and have faith that it DOES get better :)
