Any advice for a vegetarian who wants to start eating meat?

I'm 13 years old and I've been a vegetarian for 5 years. I want to start eating meat again, but I'm afraid I won't be able to. Any suggestions?

I am a proud vegitarian, but i saw a nutrtionist and she said if i wanted to start eating meat again to start eating chicken and fish for like a month like gradually, like one time a week, than, 2,3... than add pork , and if you feel like you're okay after a few months, add beef. if you fail to gradually add meat into your diet you will get a sudden shock of iron which can cause many blood problems and it could be deadly. good luck
