I relate a lot with the second thing. Happens mostly when I speak or because I see the other people eating and I feel I need to eat faster to be able to intersct with them.

Not speaking, eating alone, listening to music/news, help.

The being shown food is a difficult thing though. Taking water sometimes removed my hunger in those cases (as most times is just that).

I need to leave the place if there are people, I try to give me comfort vegan food and I watch series or films
