I think that if you
really wanted to eat differently, then you would find a way. But you're taking the easy route that doesn't really require you to think.
Making a change can be stressful at first...but if you're excited about how much better you'll be, then that feeling should overrule the "stress" of changing your habits. If you think it through and prepare for your meals, then it should be a fun and interesting transition.
If your parents cook dinner, then it helps if you start focusing on the "sides" instead of
meat as the main course. That's how I did it. I just decided to start eating more vegetables...so I started making my own salads every night. And then I started adding more and more vegetables to my salads, until the salad became my main focus at dinner. And after adding some protein (like kidney beans, chick peas, sunflower seeds, almonds, or walnuts, I wasn't even hungry for anything else. So... eat a salad first, then if you still want something else, eat one of the side dishes. Usually they're very easy to convert to being vegan-friendly. Sometimes all it takes is removing an ingredient, or replacing it with a different version (like veggie-meat or veggie-cheese).
