It is really up to you whether you continue to pay for lyiing or not. It is also up to you whether you take positive or negative action.

so which is it to be
you can lie to others even maybe to yourself but let's get one thing straight, people who are healthy(physica;;y & emotionally, do not do or say this:-
"i'm not sure I want to stop anyway. And I am physically 100% healthy. But I do this 1-3 times per day now." or this
"besides, I am a pig, and pigs stuff themselves and can't help it."
if you are truly a pig you can make a fortune as pigs can't generally use computers!! You were born human not a pig so use your mind & decide whether you want a real life or not & whether you want to actually do something about it or not??
Much of what you said is true about people not having a clue about eating disorders & about people telling you you're fine instead of asking, but I really doubt that they could fire you for lying to one person especially f you told your boss in order to get the time off to see this psychiatrist
