Blood is thicker than water... right?

I look at this saying, and I debate over it's meaning. I don't know if it's the fact that it seems like all my family has gone away or the fact that I have had strangers take care of me better than my own family has, but all in all I don't really agree with this. I mean I guess family is supposed to be more reliable than your friends, but what happens when your friends are more reliable than your family? What happens when it seems like all you have is one person, and they are in no way your family? When does water trump blood.
Ive been without any sort of a biological family since age 12. When I lost my mom, I never thought I would be able to move on. I was so hurt, and I still am. In a way, it still doesn't seem real. On the other hand, my heart is still broken. I've tried and tried to work things out with my aunt, because she reminds me of my mom, and it just doesn't work. Beyond that, many people who have entered my life feel like my family. I know that I've had a few good friends that I wish I had as family, and I know they are a gift. Maybe God forgot. Charise Tea, is definitely one of them. I had met her my sophomore year and we became inseparable. She made me laugh, and we had the funnest times. More than that, her family treated me like I was family. Her mother was so giving, and her father is one of the men I respect the most. They stuck with me thought the transition of homes and always held my hand when I needed it. They supported me and let me have experiences I will never forget. The main thing that made our relationship so great was that I knew that I could always tell her anything. She was my rock, and hopefully I was a rock for her too. In this situation, water was definitely thicker than blood. She will always hold a special spot in my heart. Second, a girl that I met freshman year. Jaymee Hallmark. She has changed my life. When we first met, we would do things like the movies and go out to lunch and what not. Then things got a Little rocky with both of us, and we lost touch for a little while. After we began to hang out again, I knew I had a real friend. Through thick and thin, she was still there. When my foster mom went crazy and I needed a place to live, she was there. First, I was just staying with her. Then her family asked me to move in. Her parents became foster parents, and I now live with them. Many people told me our relationship ship would change, for the worst once we moved in. This was wrong. It has not changed at all but more or less strengthened. She is the family I have waited so long for. Her parents are wonderful people. She claims me as her daughter, and although I don't call her mom, I know in the back of my head she is everything to me. I'm trying so hard to make them proud and show them how grateful I am for everything they have given me.
In the same way, I think How could this be? How do strangers care more for me than my own family? Who ever said blood is thicker that water? Whoever it was, clearly they were wrong, and I am living proof of this. So here is, my family of water. Charise on the far right. Jaymee in the middle.
