Hey!!!

I was vegetarian for 1 year and thinking about going back!

I had to stop because of health reasons so I recommend going to see a doctor and getting blood work done to see if everything is okay if you go vegetarian!

Also you may want to wait until you live on your own / make your own food because you should convert your whole family and it's rude to ask them to make separate food for you! As well as eating at other people houses, if you do that a lot I may reconsider.

Also keep in mind that you can't simply cut out meat, you will need to find the protein in other places like in egg and nuts and dairy products! So if you have any allergies it might make that harder too!
Also be wary that you may get low on iron as well as vitamin B12 which can make you fatigued! So you should take supplements if you start feeling lethargic!

Eat lots of vegis! Not just carbs! Vegis have protein and iron that you'll need without meat!

Also if you do convince them, you might want to try cutting out meat gradually, like maybe cutting out red meat, then chicken, then fish to see how it goes and make it an easier transition on your family!

And there's more things than you realize you cannot eat when you're vegetarian!
Gravy, stuffing made inside a bird or anything that came into contact with meat products if you wanna be strict vegetarian.
I would recommend waiting till after thanksgiving / Christmas! Trust me you'll miss out!

if you have any more questions! Or anything I'll be glad to answer!

But yeah if you're trying to convince your family, tell them it's completely healthy and safe if you're eating properly and maybe make all your own meals too so they don't feel burdened!
If you need a recipe for a super yummy vegi sandwich! Lemme know I make the best hahahaha
