It is not really that hard, especially if you are already a vegetarian. Stop telling yourself its hard. If this is your senior project you should have academic energy to put into research of things like vegan substitutes (vegan cheezes like Daiya or Kite Hill and Boca burgers) or natural replacements (nutritional yeast, tofu, cashews, and seitan). You can use your project as an excuse to watch The Vegan Zombie (this really cute 20 plus year vegan in his early 40s who looks like a more approachable or average looking Jared Leto and is just really super sweet and knowledgeable). I was self-employed when I went vegan so I spent a ton of spare time watching vegan YouTube and I still have Pinterest boards that would make any Millennial proud. Cut out this tv show you think you have to watch or this obligation you really don't like anyway, and devote it to watching vegan shopping and cooking videos or reading blogs.
I know dairy is addictive. I know. But it doesn't actually help you with your problems like alcohol or cocaine. I'm not even trying to be funny, I think it should be easier to kick milk than cigarettes. That's why you always seen Joaquin Phoenix smoking. It's not because vegans are some perfect beings immune to emotional crutches or addictions, but more like we live in the United States, you really don't need that fast food, there are tons of other things you can eat. I find arguments that challenge veganism more relevant when they actually discuss developing countries where vegetarianism really does seem more feasible. But we here in the first world have plenty to eat, we have so much choice, and in the end, we are really doing the most damage with our entitled greed.
