Life is too short to live with regrets

In my short lived life of only 16 years, I have grown to believe that I have experienced many tragic and life changing things. There has been many times where I have said to myself things such as, "I wish I hadn't had done that" or, "I wish that never happened." Though I have never really been faced with the actual question about something that I regret or would take back, simply because that just does not happen in life. I have been through so much in my short life that it is really hard to pin point one particular thing. Sitting here writing this, is really giving me the opportunity to think deeply about mistakes I have made, or promises I have broken. There are many thing I wish I could take back or prevented from happening though, most things ave been beyond my control. Something that I could have controlled was whether or not I chose to go home. Today I live with my mother, brother and now step-dad Tom. I have been home for a few years now and just like any family we have our ups and downs. I really miss my old family though. A few years ago, I was about 8 years old and placed into a foster home. This wasn't like any other foster home because they are honestly considered my family. I miss them more than anything and they have influenced me to be a better person and do well in all that I do. I was always given all the things I needed as well as most of the things I wanted! Before then, I have never had an actual family. Even though now I see how much better off I was, and how happy and healthy I was. Being as young as I was, my mother was my world. I missed my mom more than anything! I wish I would have known what I know now, because maybe I would not have made the same decision. Don't get me wrong, I love my mother and my family with all of my heart but I will always have that doubt in my mind. Doubt about myself, my brother and my mother. Would we all be better off? Would my brother have dropped out of high school? Would I struggle with the things that I do? Would I still be in Early College? Would I still leave in such a poor beat down neighborhood? Would my mother be healthier? All these things almost always cloud my mind. Though this is something I'll never know. I am not sure that I regret my decision, I just do not like not knowing. The decision my brother and I made not only affected me, it effected everybody. My brother, my mom and especially my foster family. These people were planning on adopting us and it is said that their family fell apart once we left, due to heartbreak  My foster parents split up, they quit fostering and now the whole family is set up on scheduled visits. I regret making the decision. I regret not knowing.
