Picky eaters

I myself am a picky eater and a lot of people say "just eat it you get used to the taste" and No you do not. Even in kindergarten I was very picky I got forced to eat things I didn't like because of course they thought ut would help raise chaoldren to not be picky eaters but I did the opposite. Till this day I will gag at even the smell of real milk (I am not talking about lactose free milk that one smells a bit different) but also just looking at any type of milk too it just makes me gag. 

I think a lot if people just don't understand that even smelling certain foods makes you gag and almost throw up like I hate cooked vegetables some make me actually sick for example but I love raw vegetables.

"Just eat it its not that hard" it literally is what do you want me to order a 50€ food that will make me sick and that I don't like instead of the cheaper food that I actually enjoy and I'll have fun actually eating? Why do you wanna ruin eating for me as long as I'm not super unhealthy like get off my back I'll eat what the fuck I want.
