Kill it

Okay, don't worry, the best thing to do is:

1. Stop playing Minecraft.

2. Get a life, where you can experience real farm animals and grass, not pixelated ones.

Get rid of all your mods. I find that my minecraft doesn't want to work if a have mods on it.
You also may have way too many maps and/or stuff on those maps.

If you are playing on a modpack, reset it. (Delete and then re-install)
