I have ADHD which causes me to have sensory issues as well. When I was a child I could only eat highly processed meat. I went vegan at 17, I’m 25 now. There’s still things I literally cannot eat, i.e. oranges, even though I love orange juice, but the orange texture completely closes off my throat and causes me immense anxiety, which neurotypical people will never understand. I hope for you to be able to find another food you can deal with. I was never into meat, because the taste and unprocessed texture also cause same reaction like oranges in me, but the lingering taste also makes me want to puke, so not eating meat is very easy to me. I have similar response to other animal products, where the taste and/or texture, especially the lingering taste, cause extreme disgust in me. I cannot eat some products mimicking them because of this. What “helped me” personally was becoming so poor I was only eating pasta with tomato sauce, which I’d put through a thin-eyed sieve to make it smoother. I still sometimes get overwhelmed by textures of leafy things which cannot be properly broken apart, but that’s why I try to juggle what I eat. I cannot do meal prep where I’d eat the same thing every day, least I get sensory overload. I’m sorry for what you’re going through and for insensitive neurotypical people mocking you for what they didn’t experience and cannot muster sympathy for.
I fantasize about a bidet a lot. Alas, a poor rentoid I remain. I fear breaking sth and lack tools to mount it myself, and cannot afford a service of someone who could do this.
