Hi Spooky_Monk
A lot of phobias or extreme aversions has to do with some form of a negative to a traumatic experience in early childhood.
For example some might be afraid of water, either because they watched too much horror movies involving water or one nearly drowned to death. Others are afraid of dogs because of a sudden loud bark giving them a bad impression of dogs or have seen a vicious dog attack.
Maybe in your case, you might have had a negative experienced which from then on made you self conscience or fearful of eating before people.
