It's very interesting (and infuriating) how many people really don't understand what the OP has very clearly described and are turning it back on to OP as a personal failing or medical/psychological disorder. I've known determined feeders like this and they quite probably believe the same - that their target has some kind of disorder - rather than understanding that the problem is their own crossing of boundaries.
From the feeder's POV, they are not willing to let you have the choice of saying No - your only choice is in which foods that you don't want you will be expected to eat vast quantities of.
Yes, you can say No thanks to these people, but THEY IGNORE IT. Your only options are:
- Accept everything they offer (and the more you accept, the more they will offer);
- Tell them outright to F off or throw the food back in their face (not great if they're family or people you otherwise like and want to stay friends with - and that will only convince them more that you must have an eating disorder anyway);
- Avoid them
Offering your guest food and drink periodically is a normal, kind thing to do as a host. Politely accepting or declining offered food and drink is also a normal, kind thing to do as a guest.
However, when it turns into a form of relentless bullying (whether the host realises this or not), it is NOT normal, reasonable or acceptable - and it is a form of controlling.
Substitute 'food' for 'sex' and the different endless food options for all manner of possible sexual acts - when you've clearly said No - and imagine if it was a partner (or hopeful 'suitor') instead of a friend or family member.
Are you really just saying that you would happily stay with/get with them? You'd just keep saying No 50 times and batting them away every time they ignored that your clear, unmistakeable decision is NO and indicated that you must be frigid or have a sexual dysfunction - and you would still believe that YOU were somehow the unreasonable one for seeing this as a problem? It's exactly the same principle.
