if it’s just because of sitting alone i think that would suggest more of an anxiety or social disorder of some kind. if it’s like what number one said tho than i would lean toward yes an ed. that all being said, take anyone’s advice off yik yak with a grain of salt and pls do research via vetted sources on google (NOT chat gpt). if it is truly preventing you from eating in a public space (a regular activity), if affordable/accessible reach out to a therapist and/or primary care physician.
