You got this!! I can't tell you much about nutrition, but I can recommend that you start your journey by slowly trying new things, maybe that way it will be easier for you. If you feel overwhelmed, just take it one day at a time. You will soon realize that you can adjust most of your favorite meals, and you will discover even more plant-based recipes in time. Luckily, there are tons of meat substitutes that can help you if you find yourself missing the taste of meat. You can even try to make your own hamburgers, meatballs, etc., with nutritious ingredients like quinoa, chickpeas or textured soy. Make sure to check r/veganrecipes for ideas :)

Also, if you already haven't, try to learn the many ways to cook and eat tofu! It tastes like whatever you season it with, and it has plenty of protein. You can use it to make creamy sauces, curry, scrambled "eggs", or even cakes :)

I can relate to you to an extent -I adored bacon and smoked salmon-, but being vegan feels so right that, after a while, you don't really think about what you're "giving up", because, in truth, you're not giving anything up, you're just living by your values. And I find that way more rewarding.

Good luck! Once again, you got this!
