Trainspotting
A masterpiece of a movie that explores how the disease of addiction influences ones environment and vice versa. It shows how immensely difficult it can be to stop letting other people run over you and start choosing to live your own life, even if it means you have to turn your back on your loved ones every now and then. This is a problem especially prevalent among people who struggle with substance abuse, but I think most people will be able to relate, albeit with a bit of effort/imagination perhaps
