Getting help: A vivid imagination and delusions are two very different things. If you have actually suffered from delusions and loss of ability to determine reality, would encourage comprehensive evaluation by a psychiatrist or a clinical psychologist. If it is just that you love to live in a fantasy life - then you need to make a decision as to whether you want to live primarily in reality or fantasy.
