I haven't really posted in this forum much myself... but
to the wonderful veg*n world! For me, the hardest part about becoming vegetarian (and then vegan too) was deciding to do it. Everything else has been deal-able.
If you're keeping an eye on nutrition deficiencies, start tracking your food in FitDay/DailyPlate (if you're not already). It's a good idea to at least check a few days randomly in the beginning, just to make sure you're staying healthy. And that way, if anyone says, "Where are you getting your protein/iron/random nutrients from?!?" You can say, "Actually I'm getting plenty, thanks for asking."
