Vegan to meat eater

So I'm a dancer and I recently severely injured my foot and my doctor advised me to stop being vegan to try to heal it faster. I'm trying everything I can to be able to dance again and even though it goes against all my moral standards I know my life would be gone if I couldn't dance. So it's been three weeks since I started eating meat again and I feel awful! It upsets my stomach I feel sick everyday and it doesn't even taste good. I know that this could really help heal my foot but is it worth it?
