I'd definitely try to be vegetarian first if I were you, especially in the circumstances you mentioned.
Since you encountered some opposition already, I suggest you take up cooking as a hobby. It takes some time and effort to get the hang of it, and you'll have to spend some more time finding decent recipes as well (the "Recipes" section here is probably a good starting point). But you'll see that for most dishes, the ingredients are quite common, and the key lies in the spices and sauces you use. The can provide a wide variety of possibilities.
In any case, don't let anybody get you down for this.
