Help with becoming a lacto-ovo vegetarian. Please?

I am an lacto-ovo vegetarian and i live in a family of meat eaters. i made my choice when i was 11. i am proud of my decision and i stand by it. for telling your parents, don't beat around the bush, tell them how you feel, they will understand. as for the age, to me it never mattered. the pros are what you make them and your cholesterol will benefit, cons are smelling bacon in the morning. ;P You would be lacking protein so i would suggest protein bars, i have these really good Chocolate ones. if you are worried about home ec get there early on the first day and explain it to her, she will understand. i don't eat any type of meat-meat. meaning cows, chickens, lamb, pig, and anything else someone may eat, but i do eat some seafood. some suggestions i have for you do you make the change, i keep that as need to know information, get to lunch early so you can get the veggie meals if you buy and don't let anyone make you regret the decision.
