I have an eating disorder…

Hey! So i have an eating disorder. If anyone wants to look it up, it’s called ARFID. Shortly, i am very triggered by foods like i am somewhat traumatized by it and totally freeze and just cant eat. Not necessarily about the taste. I am very very limited in what i eat. I am a little scared of going to korea for that reason, as i have no idea how it will be food wise there. I do know that there are western restaurants and like familiar foods that i am used to in Canada, i also eat spicy ramen but mostly with not much stuff in it. Can anyone either reassure me or give me recommendations? Also i would be going alone so i have heard that some places refuse solo people. If anyone have recommendations for that too :) Thanks so much guys! <3
