I knew someone who went over a year without solid food. They have only recently started introducing solid foods, which is slow and very controlled.
They were diagnosed with Avoidant Restrictive Food Intake Disorder (ARFID). It caused them, through this eating disorder, to struggle to engage with solid food.
Of course I'm not saying this is what it is (I'm not professional!), and I wish you the best in your journey. What I want you to know is there is so many good professionals out there, as well as liquid based foods that act as supplements in the meantime. Be the best you can be and enjoy life as much as possible as you conquer it.
All the best
Very sorry you're living with it in your household. It's a such an incredibly powerful thing. I couldn't believe how texture, colour, presentation, sound - so much! - all played into making life difficult.
We take a good meal for granted.
