you just have to make your feelings of love for animals outweight your desire for flesh.. watch more videos and maybe read some books, on the topic of animal cruelty.
I'm not sure guilt is a long term motivator, though. when I went veg in 198---never mind the year, I had no mock meats (and didn't know about Worthington... don't like them much, so it was probably best). only tofu available was soft. again, not a fan as a meat sub. What I began to notice was I missed the "fixings" of meat: the sandwich toppings, the sauces. So I developed reasonable subs for the sauces that were not veg-friendly and collect the ones that were. I got into interesting veggies and breads. I got into diverse ethnic foods. (I grew up in a tex mex town) I got into Krishna cooking, which is heavily dairy and sugared, but that's where I was then. I had many a cheese sandwich when the family was having burgers. today, I have awesome veggie sandwiches, and I'll grill the veggies at the same time. with a foil "splatter guard." I discovered different food so that I was not simply eating a mock. So, instead of McD, hit Wendy's and get a baked potato. Might want to find places that have salsa packets and keep that with you for places that only have dairy toppings. A baked/ jacket potato with broccoli and salsa (or the buffalo sauce they have now) is pretty good and allows you to socialize with your omni friends. Having a level of acceptable foods for home versus out can help. I'm lacto outside of my home, but a touch more flexible dining out, IF there is not a vegan option. I steer groups to places where I have more options, though.
your best bet is to eat fresh rawer foods and not so much soy. go for local in season foods. like right now i have some spinach leaves, fresh whole mushrooms, carrots, potatoes,sweet potatoes,plantain bananas, peas, bean sprouts,whole green beans,onions,tomatoes, turnips, lentils, beans, rice,whole wheat homemade pasta, oatmeal, cream of wheat, whole grain bread,pita bread,organic hummus,chickpeas,homeade tomato sauce, pumpkin,olives,organic veggie stock, flour, sugar cane,and every spice u can imagine. this will feed me for two weeks
