Vegamy, you're not alone. I've had these sorts of feelings since becoming vegan. They seem to get "worse" (i'd rather call them, "more intense") as the days go by. Some days I can stay in a positive mood and hope that my choices help save animal lives. Hoping that my choices, and when I have the guts to speak out to strangers/family/friends about veganism, will get them to make the switch the veganism (or at least try it), and save animal lives.
Sometimes though, I just look at everyone and frown. For example, today on the subway, I was on my way home from work and these three girls my age were wearing leather cowboy boots and leather jackets. They were all laughing and having a jovial time, but do they know the Indian cows that were used to make their garments and boots endured a gruesome death march and endless abuse on their way to being slaughtered to be made into said garments? Maybe they do, maybe they don't. If they did it's obvious they didn't care.
I try not to judge people but now that I know the truth (and taken the red pill- matrix reference ftw) there's no turning back. I can NEVER eat meat again. I know some vegans crumble under stress and other pressures, but it's impossible to go back after all that I've learned. It pains me to no end to see my fellow human beings, my species, be so ignorant and blind and show no compassion whatsoever to those other earthlings who share the planet with us.
I'm sorry for going off on a tangent vegamy, but I just have to say I feel the same way as you. I've even had some women interested in dating me and possibly engaging in intercourse. I only mention this because I show them zero interest and honestly don't even want to have intercourse with them, if you can even believe that. I'm not sure if that's a bad thing, to see my sexual libido drop since becoming vegan. I find nothing sexy about people who don't have compassion for animals. Yes, I did ask these women who are interested in me about their thoughts on veganism, none were positive.
