Bagpus, how awful for you :(
Apologies if I have the wrong person, or if you didn't want it mentioning on another thread, I honestly can't remember if it is you who lives a sub life for want of a better phrase of it on here but I think it was, if so could your master not help you with food very specifically as part of life play? I appreciate he probably already is helping with the anxiety issue area and thus possibly doing this as well anyway if you are living 24/7.
Apologies if it's not you, and please don't derail this anyone else, this is a serious suggestion to help a member.
