2nd Book?

I used to write about love and heartbreak and all that stuff in between, then I recently got my heart broken again, and I'm not sure if I want to write about it. It has really taken all of the writing out of me to be honest. I don't want to share this particular heartbreak with the world, which I guess means the ones that I had before were superficial is I was so capable to reaching back into my emotions and pulling out the feelings I had. Right now, I don't want to touch them, they are sacred really, between him and me, and I really think I want to keep it that way. The problem is I'm supposed to come back with a second book, and I'm sure I have enough fodder to fill it, but I just can't bring myself to give up the happiness that I felt then and the heartache that I feel now. Is this a form of writers block? I'm glad I'm indie because if I were dealing with a major publisher I wouldn't have a choice, feelings or no, I would have to come up with a second book, just as good, in the time frame

aloted, or else. I don't think I could work like that. I do however have other journals that I've kept and am compiling and developing at this time for a book, but my feelings of most sincere love for this one person, will stay between me, him and the Lord...I'm selfish that way.
