I just went vegetarian today, need advice?

I just went vegetarian, and I'd like some advice. I absolutely adore animals and can't stand the thought of eating them. Also, my grandmother is very un-supportive of me. Last time I went vegetarian with Peta's pledge, she kept telling me to just take "one bite" or just "try the donuts with lard- they're a lot better". Lard is disgusting. And she would purposefully give me bacon for breakfast if I spent the night. Also, she's always like, "just one taste, I won't tell anyone." Or, "how do you do this? You've GOT to miss meat. How about I just make some steaks? oh, come on!" I need help!
