Hi there Caiterz,
I'm a picky eater, with ADHD. That comes from my mom's side and there are also autism spectrum cousins. I have similar sensory issues but not enough to qualify for full diagnosis. I too, struggle
There has finally been an uptick in recognition of SED (Selective Eating Disorder) and ARFID (Avoidant Restrictive Food Intake Disorder) in society and online. Here is a Facebook group I like for adult picky eaters.
www.facebook.com A great bunch of folks. There are other FB groups, and online resources as well, and I'd be happy to share more that I know of. I'm even starting my own blog but don't have much material up yet.
It seems to me that on this 3fc forum those of us with sensory difficulties with food tend to be in the minority and people don't always know how to give advice that we can really follow - but I hope that will improve as the knowledge in society improves. In the meantime, I wish you the best, and again, contact me if you want to know more of the discoveries I've made in this area.
