I think that your reasons for being a vegetarian become relevant here. No one wants to feel deprived, or like a martyr, even when they’re acting in ways that align with their values.
If you don’t eat meat because of the farming conditions, then maybe try meat that is grass fed/cage free or grown somewhere locally where you know that the animal was well cared for and died in a respectful way.
If you don’t eat meat because of the disproportionate water and land resources it takes to grow it, then stick to meats like chicken that don’t require fewer resources to grow.
In general, try to find clarity about why you aren’t eating meat, and find a way to align that value with not feeling deprived or unhealthy. Balance is the key :)
