Daydreaming

Since I was little, I always used to daydream a lot... It was always normal for me, but since I have DP/DR I'm asking myselve why I do it? It's thr only nice thing in my life... I ask myselve why can't things be like in my dreams? I always get so sad when I stop daydreaming, because my life is so boring and not good to live... I always have to force myselve to stop doing it... I'm scared that I'm trapped in my dreamreality
What should I do? Can anyone relate?
