Hi mollykins,
I dont see the point in you going veggie, as others have said you seem to be making a lot of excuses not to!
Just eat what you want to eat and when you want to eat it!
My best mate went veggie around 10, and she is now vegan, same as my cousin but that is because they have ethical reasons. There is no point saying should I go veggie just because you dont like some meats but will still eat them at other times when you have to. I dont like certain meats, but would never beecome a veggie, and I even had people trying to force it on me when I was studying animal car at college!
So, to sum it up, no you shouldnt become veggie, you should just eat what you want when you want and if need be make your own lunch and learn to cook for yourself!
