I second what xrod said: it's systemic--and I couldn't put it any better than that.
First, as xrod said, get yourself set up with supplies: energy bars for snacks, "instant" vegan meals for emergencies, and getting accustomed to preparing your own meals--whether that meal is a sandwich (everyone can make a sandwich!), pasta, veggie burgers, or what have you. If you can, hook up with someone you like that can show you how to prepare a nice meal--it's what I did and I learned about chocolate covered almonds stuffed in pitted dates--whaaaaaaat?! Delicious!
Second (as others have mentioned) stay informed: read, watch videos, participate in on-line discussions (like this one--so kudos to you!). Whatever you do, don't let the information anger you when you're having a discussion with a non-vegan. You know why you're right. Getting angry with other people doesn't help. You're cool.
Third: inform yourself about 'complimentary' information: on a sustainable vegan diet your body becomes primed for maximum health. What else primes your body and pumps you with energy? Learn about how you sleep and/or what amount you need (it's interesting!); study fitness, nutrition and training (there are great YouTube gurus for this--I like Scooby1961). It's so interesting!
Fourth, and this may seem far-out--spend time with animals. They are awesome, loveable, intelligent, warm and responsive. They're not shoes, or bags, or clothes. But you know this. We all do--which is why we're here.
