>>2705678If you have to survive socially in a city, try to be as honest as possible about your eating habits and be prepared to be judged by a jury of your peers for digressions that you've made. Just be open about it, it's that aspect which will speak for you. The more you've digressed from the path you've chosen, the harder you'll be judged, so if you digress a lot, be prepared for a lot of heartache. When not being judged, eating protein-rich and fat-rich foods such as nuts and fruits help, but remember, everyone only survives until they die, which happens to everyone.
If you want to survive outside of a city as a vegetarian, like, on a long hike or a camping trip or something, something in the woods, well, I don't have much experience with that. I remember that when going camping I'd just eat meat and relax the vegetarian habits. But that's not what you're asking. Oh wait I do have some experience with it! Nuts and fruits were methodical, and it takes some discipline to not take part in a big slice of ham. Stock up on nuts, fruits, waters, vitamins, other vegetables, before you go with a meat-eating party. But remember, unless there's another like-eating individual with you, you won't do a lot of the things that they'll be doing. That wouldn't have to stop you from having fun, doing your own thing and contributing in the ways you can though. Try not to judge the meat-eaters if you hike together and instead provide them with useful boons while hiking. I only hiked one day with the party but water on a warm day is welcome to most who have forgotten to bring it, regardless whether you eat meat or not.
It can be lonely, because eating animal meat is ingrained (see what I did there?) in most human's diets, but remember that replacing animal meats with nuts and the required foods (you should be receiving all the nutrients you need whether you eat animal meat or not) puts less strain on the climate and your carbon dioxide footprint. Remember it's not a competition.1
