Ooo, that’s a tricky one. I’m a vegan and I eat a bunch of nuts myself :I Would you be allergic to almond milk? Or is it just peanuts and tree nuts?
I’m sure it can be done, but you’d have to be careful about the “trace amounts” on the labels, which is on a good bit of stuff (and it’s hard enough finding stuff that’s vegan to begin with, especially if you don’t have access to a natural foods store).
The majority of what you’ll eat is vegetables, pulses, fruits, grains, and seeds (and other nuts?) anyway, though.

Some tips: Try it for a week first (it’s what I did). You’ll initially be intimidated, but once you’re doing it, you’ll see it’s not as hard as you might’ve thought. Your tastebuds shed off like every week or so (or maybe even 5 days? don’t remember) so they won’t even remember certain things after awhile and the cravings die down. You’ll be like “meh” instead of GIMME (hopefully, lol) to certain things and you suddenly have more control over yourself. :) Milk and cheese have an addictive + carcinogenic protein in them called Casein, it’s basically the feel-good hit the calf gets that encourages it to come back for more. It’s why cheese seems hard to give up. With time, you’ll see dairy as kinda gross and won’t want it in your body (disclaimer: I’m not psychic and could be wrong). If you’re transferring from a straight up normal American diet, I don’t have any tips for cold-turkeying meat. I think it’s more of a life-long conditioning/comfort food type of thing, to want to eat it, but I was never a meat-fan to begin with so it was easy for me to dump unceremoniously. Try watching the documentary film Earthlings (for free to the public, up on youtube!) that’ll definitely help (but brace yourself… I couldn’t get past half of it, personally). It might also help to know that a lot of the flavor in meat comes from Urea (basically pee that’s still in the meat).
And don’t be discouraged by sources that say B12 only comes from meat (there’s a misconception that protein only comes from meat too. You’ll come across it a lot. The reality is, deficiency in either protein or B12 is rare in this country, even for vegans. I’m talking, a couple of case studies. You don’t need nearly as much as they’d have you believe). Anyway, B-12 actually comes from bacteria. Other sources of B12 are mushrooms and blue-green algae (and they toss some in stuff like soy milk). Protein’s in freaking a bajillion things you’re eating anyway, I don’t even worry about it (quick google on vegan protein should show you what I mean).
I think it’s funny how as soon as you turn vegan, you suddenly have to be concerned about where you’re getting your vitamins from (as opposed to before, because apparently the hamburger and fries were just bursting with nutrition!.)
In general, nutritional information is a landmine of misinformation and garbage. I suggest going through seeeveral sources. You’ll eventually learn that if you keep it varied, you’ll get everything you need. Variety’s good anyway, right? Don’t be a vegan that just eats potatoes and apples (THAT’S how you hit the malnutrition club, heh), go for the throat. Kale is excellent, sprinkle in some flaxseed to whatever you’re making, learn to cook with seitan and tempeh, explore and research. It’s kinda fun, even for a horrible cook like me. :)
And especially at first, you’ll need motivation. You’re surrounded by peers that are still eating normally, and just won’t get it (I don’t recommend trying to address that either, they just won’t get it. at best they’ll humor you), and it’ll weigh on you after the 30th social situation (food+social happens a lot). I suggest books! Lots of books! There are a bunch of vegan books, I personally recommend the World Peace Diet by Will Tuttle, but there’s even 0.99 vegan books on Amazon that are pretty complete. I also recommend the podcast “Vegetarian Food for Thought” by Colleen Patrick Goudreau. Good stuff.
Really, your enemy is ignorance. Educate yourself, from various sources, and drink lots of smoothies! (also, for a bit the bathroom trips kinda suck. don’t be scared, your body’s trying to detox).
