It's hard to meet other vegans, or even vegetarians. When you go to eat something, if it has animal ingredients think about the animals being harmed for a quickly eaten and forgotten meal. If you keep your veganism focused on the animals you won't succumb to temptation as easily. When my husband went vegan after a decade of being vegetarian I advised him to give himself a full year to transition so he won't be having issues with feeling guilty or weird when we go out to a buffet and he ends up eating cheese or something along those lines. I'm always prepared with vegan snacks in my purse, and even keep powdered coconut milk with me to use as coffee creamer when I go out. It makes my life a lot easier as a vegan.
In regards to meeting other vegans irl, good luck! I only know three, and the few that I've converted from veg to vegan.
