Gyms

i accidentally put my pokémon into a gym, and i want to take it out and it wont let me, which is very upsetting. Please fix this because it wont get kicked out. i live in an area where there is no one who plays pokémon go but theres still a gym. i would like to use my pokémon for other things rather than it being stuck in a gym...
