I'm so worried..

I went to work all day and barely got to spend time or see my dad today. I'm so worried about what's to come. I know everyone says that this is the time to be happy and spend more time with my dad but it's so hard when I know what to expect. I'm worried for  my mom. She seems strong on the outside but I know on the inside it's tearing her apart as well. I wish my dad could stay at least a year or two more so he can see my little sister graduate and to see my nephew grow up..T_T..The guy that I'm talking to has been on and off again. Why do people keep coming in and out of my life to hurt me? I don't want anyone anymore. My dad's the only male I need.
