Some days are better then others

Things have been tough lately, I am just so tired. I sleep fine, but it's an exhaustion that never seems to go away. I am emotionally drained. I miss my mom, and I miss my Grandpy. They would know what to do/how to take care of my grandmother. It's been almost two months since my grandfather died, but I feel like it happened so long ago. Minutes feel like hours, hours feel like days, days feel like weeks. It's so strange. I feel like the last day I saw him, is just a faint memory. I don't know if it's because it is too painful, so I am trying to bury my memories of him, or if it's because I am so stressed out all the time. Everytime I see pictures of him and I, I wanna cry. Life is so unfair.
I am trying to pick myself up. I just don't know where to begin. I need to go back to school. I never reapplied, for fear of failing. So much loss in my life; a few friends, alot of my family, and with every new death, a piece of me goes too. How many more people have to go, before I have nothing left?
