Does my mom just not get it? I don't want to eat dairy anymore!?!

Just explain to your mother that you would appreciate it if she didn't throw dairy products in your face any more. Although I disagree that you should eat dairy during Christmas dinner. Not to sound rude, but you aren't the only person in your home, correct? I mean your mother obviously eats dairy and so do your siblings(if you have any). You need to learn to live around what the other people in your family eat and stick to what you want. They are always going to be having meals that you can't have, and you can't expect them to pick up your diet with you. If you need to, you can make your own vegan friendly meal to have while they're enjoying their meal. I'm only saying this because I am currently going through the same thing, but I'm vegetarian, not vegan.

Again, I in no way wanted to sound rude or unsupportive in your choice. I am just trying to give you my honest opinion

I am a Vegan, and believe that you should stick to it. She may be trying to test you to see if your really going to stay with this. Also you can always just go to a super Walmart or something, they have great almond milk there, and a mini section dedicated to Morning Star, a vegetarian and vegan microwaveable food brand.
P.S I had the same problem this Thanksgiving, basically I just heated up a black bean Morning Star Burger, and had a tofu shake with it.

Experiance

I think it will be very much the same as with you as you both have to learn what you can eat and what you shouldn't eat. Don't expect her to change her own cooking style just for you, or to cater just for your whims.

Go over the foods with her and show her how much she can no longer you want to eat.
My guess id that you will have to spend a lot of your own pocket money on those foods she will not buy.

I don't know where you got the idea that you can just order your Mom around and demand she make specific foods, but that isn't how life works. You sound like a spoiled brat and I feel sorry for your mom.

my parents are like this too
they can never get something through their heads

my parents do this too

Did you explain to your mother why you are becoming vegan? This is important in becoming an adult and helping other's respect you as one. If you talk to your mother and tell her why you want to stop eating dairy and tell her you are taking a multi-vitamin or other ways you will get the proper amount of calcium in your diet she will likely respect your decision as someone who is capable of making adult decisions.

Having a set time to change is sounding a little wishy-washy to me, holidays always hold a LOT of value and celebration surrounding food. So do your best to stick to your values and be open and honest with people without being rude.

Vegan

Actually you don't seem to get it that you are a baby living under your mother's roof and under her rules> You said you made your own meals but never said you actually bought the food yourself. Nope, you just used your mother's money to buy your food, used the gas/electricity she pays for and pots and pans too probably to cook them then went on the internet and asked if you mother is ignorant and allowed complete strangers (who could be pedophiles for all you know) to bad mouth her like you did so you can feel self righteous and good about yourself.

You are following a diet, she is trying to feed a family. Your wants and desires and new "cool" lifestyle pale in comparison to her responsibilities. Plus having an ungrateful daughter. If you think you know better. move out get a job and be all the vegan you want to be.

I had the same problem. I was vegan for a year. Well let christmas be the time you enjoy yourself and not worry about eating right. Let your mom know you are who you are, and you dont appreciate her throwing the dairy products in your face. If it doesnt make you happy let her know. I guess she's trying to do what my mom did. (Making sure you're serious) You can't blame your mom. All mom's worry about little things. Just sit down, and have a heart to heart talk about how you're feeling about it. I'm sure she'd understand. Hope I helped=)

My opened, and very odd, but truthful mind...and experience, but my mind is waaay better=)

do what ever you feel is right, i suggest not because your probably too young to go and buy replacement nutritons that dairy provides humans with. so yea i dont even see why dairy products are bad anyway, meat is understandable but dairy?

Hmm....perhaps you could offer to help your mom cook Christmas dinner and make dishes vegan. If you can get soy milk, you can bake with that (quantity-wise, it's interchangeable with cows' milk). If she offers you something with dairy, you can politely say no, thank you. Since you make some of your own meals, presumably you go grocery shopping as well, right? You can buy what you need to make vegan foods and make them available for the family.
