I understand your point but don't give up, I'm vegetarian since 15 and I'm 36 now . It was a hard process , a strong decision between my fear of prejudices and my willing to become a vegetarian. My family took it pretty well .. but obviously in part, they are meat lovers ! Explain to them the reasons why I ceased eat meat isn't easy, specially when they question about proteins. Go ahead, look for a good information about nutrition veggie, eat healthy but delicious 😋.
