Vegan in process

I have been a vegetarian for the past 3 years (in October). I have been working on being a vegan for the past 2 years. I continue to have trouble with dairy. Cheese is my downfall and I continue to eat it. I also eat seafood. Technically I can’t be called a vegan. I am putting myself down every time I eat pizza with cheese on it or have a veggie sandwich with cheese. I feel like a failure when I can’t adhere to veganism. I am coming to realize that maybe I should be labeled vegetarian and if I choose not to eat the dairy products…all the better for my body and the planet.
