eating food

okay so i have no clue whats wrong with me or if alot of people think this way. but since like 7th grade i actually can not speak about food with people (unless its my family). but like in spanish class last year we had a whole lesson on food and i couldnt do it, and felt so embarrased when the teacher called on my to answer a question or say my favorite food. like it feels embarrasing for me to talk about food. like in a movie if i see people talking about food with someone i forget its like a normal thing. i also dont eat infront of people like it just feels embarrasing to me even though its a totally normal thing. i mean maybe my ed has a role to play in this but like still. i can not go my whole life being embaresed to talk about food. HELP!!
