What is the name of the movie where a woman was placed in a mental hospital even though she wasn't crazy?

i don't remember much about it except it was a grown woman & she was sent to a mental hospital because they believed she was crazy even though she wasnt. she met another woman there who was actually crazy & fought with the people who worked there. one day when they were at recess or whatever, the crazy woman helped the non-crazy woman escape by running & distracting the guards. it might have been a lifetime movie but im not sure. please help && thanks in advance! p.s. the whole movie doesnt revolve around her being in the hospital, thats just all i remember.
