By the way, I don't consume milk or meat for pleasure. It's for survival. It's food, it's fuel that makes me feel better than let's say cookies or bread. It's food chain and humans are on top of it.
Tbh I'd recommend you talk to a doctor/nutritionist about going vegan. Making sure you get all the nutrients your body needs is essential, but can be very difficult for someone without vast knowledge of nutrition.
That basically applies to everyone not just vegans. As a vegan you just have to make sure that you supplement VB12. Doctors usually don't have the nutritional knowledge to help you put a healthy diet together.
