Withdrawing, pulling away to avoid pain

In a strange mood tonight. I wrote some about a period of time that Don was not sure about love and how Josie was very much in love with Don. I wrote about how hard it was for her to love him and for him not to return her love. I guess I can only explain my mood by this event. I am trying to so hard to pull my readers in, make them feel what the characters are feeling. It takes an intense passion to do that and I become intensely passionate about what I am writing about, so that my feelings carry over. It seems as if this passion, these feelings consume me and take over the way I am feeling in real life. I feel like I should withdraw for a while and concentrate on my book. I want so much to finish it. I will have to wait and see how it goes I guess. Maybe that is not how I really feel, because it is how Josie felt in the part I wrote tonight, she wanted to withdraw to shield herself from pain, hurt when Don did not return her love. Odd huh?
