I think what I have to learn to do is to get to know me, what makes me happy, do things that make me happy. I need to develop interests and continue to do them involved with someone or not. I am in the same boat. I married my birth father (not really but I married a man just like him). Unfortunately. Recently separated and I am going on a year long deployment I don't really have to worry about meeting someone at the current time. I figure I have a year for me. Sometimes that sounds great and other times, I don't want the time but I know I need it.
I can totally relate to the thoughts going around in your head at night!
