This has been driving me nuts for several days now!

Trying to figure out the name of this movie. I believe it's from the 80's, "maybe" early 90's. The premise is that a young, teenage girl who was sent over to America during the WWII returns home to England. She is sent to a boarding school where she does not fit in at all. She sneaks out with a young boy who shows her this old house, that she subsequently starts to paint, stencil, redecorate. When she can no longer stand the torment she faces at the boarding school, she sneaks away to her house while she is sick. Her mother finds her and eventually she is allowed to attend a school with her friends where they can work with their hands, animals, stuff like that.

I thought it might be a disney movie, but I can not remember to save my life! Any thoughts?

Thank you!!
