I've been vegetarian for around 3 years after I discovered how badly we treat animals, and also by connecting meat and animals in my mind... Realising that the same pets that I adore are the steaks that I ate. But still, I went vegetarian because I could. I could manage to find time in my life to change my diet and to make sure I had no deficiency in nutrients...
So don't be too hard on yourself mate, your situation is totally understandable! Actually I strongly disagree with people saying that anyone could become vegetarian if they wanted to, it takes a lot of thought, trial and error, time and obviously a lack of allergies...
Saying that, anyone can fight for animal rights in their own way, being vegetarian is only one of the many tools we have...
I'm grateful that you say that (not OP). So many vegetarians/vegans are convinced anyone who isn't vegan hates animals, or is at least "worse" than them on some magical scale they came up with.
I fought for my state's free range chicken law, but I wouldn't fight for bans of consuming chicken or eggs. I would love a law that banned chick-killing (the practice of immediately killing all newborn chickens of the "wrong gender" when reselling chickens to farms or growing egg breeds). I'm sure they'd find a way around that. Despite that, I'll still eat chicken.
