There are a ton of resources online to offload the thought required to make meals that hit your micronutrients. The easiest and most well-known is probably veganuary. Most people participate in January, or at least that’s how it started, but you can access their resources all year.
Most people don’t go their whole life never trying new food, but even if you do you only need to make the transition once and then you can continue with the same recipes every week forever.
I’m incredibly lazy, have arthritis at 26, probably have some mild anxiety/depression that comes up periodically and is untreated, but still am vegan because we all have to be. 3 years in and my life isn’t any more difficult because of it, it’s just better all around to not be reliant on killing/exploiting animals.
My blood pressure improved after going vegan, some of my blood tests mildly improved (I was 23 before being vegan so nothing was insanely out of whack to begin with, but they did improve enough for my doctor to make note of it). I don’t have runny shits anymore, I guess I was probably lactose interolant but I never identified as such.
