It is difficult, don’t get down on yourself. I think I had the typical vegan journey: carnist > veggie (with mistakes and setbacks) > vegan (with mistakes and setbacks) > vegan

And now I see animal products the same way you see meat: it’s just not food. It can be difficult to get there, but once you do it won’t be “the takeaway doesn’t have vegan options so I’ll have the veggie,” it’ll be “the takeaway doesn’t do any edible food”
