Same with me. I was always a picky eater.
I never liked meat because I gag whenever I bite down on fat, gristle, or a piece of bone. I like my hot food lukewarm and don't like different foods touching, so if I'm eating more than one thing at a meal, I cook and eat one thing, then start preparing the next.
I'll eat the same foods almost daily, with small variations. Right now it's toasted cheese sandwiches at lunch, Lucky Charms (dry) for a snack, white rice for dinner. Pizza three times a week, either at lunch or dinner. Right now I've been substituting eggplant Parmesan for dinner sometimes, and peanut butter sandwiches for lunch. I'll buy already cooked meat sometimes -- fried or roasted chicken, usually. Salad sometimes too, green or potato.
I'll eat some foods daily for months, then go off them, maybe for years, and sometimes come back to them again. When I was a kid, it was mostly tuna fish sandwiches and potatoes and vegetables for dinner. I've gone off vegetables pretty much the past ten years, though I'll open a can sometimes.
Since I'm by myself, I can indulge my eating quirks. When I'm at a family gathering or out in a restaurant, I eat more normally now. I even let foods touch sometimes
