congratulations on finding what works better for you, and proving it to yourself to boot
I'm an ethically inclined omnivore myself (meaning I do eat meat, but not from mass production/tortured animals, and not like it was never a living being. I'm not from the US or any big developed country though, so I think it's less complicated for me), but I'm happy for you (and I hope you respect your food too)
your friends might be happy too, if you let them? if you call them your friends, then your happyness should be important in those relationships. so if you tell them you found a way to be more happy with your life, I don't see why they wouldn't be able to respect your choice and share your joy with you.
but hey, in any case you have this place, and when people here don't get too wrapped up in politics they can share this joy with you.
congratulations once again
