The day you moved away was the day I lost a piece of myself. You decided you weren't happy here at home, and you picked up and moved hundreds of miles away. Although it wasn't a surprise, it was still hard to watch you go. It is still hard to watch you out there going on living your life away from the rest of us, but it's OK because you're happier there.

We were young when you left and I never understood why you would want to move away from your friends, because switching schools is hard, especially in middle school. What got me the most though, was that you were so OK with leaving your family, with leaving me. I thought you looked up to me and you just left. The day you moved away I lost my baby sister, my No. 1 fan and my best friend.

You've been gone a few years now and life without you isn't as hard. What is hard, though, is seeing the pictures you post or hearing about your day. It's hard to grasp the fact that you're living your life and growing up without me. I wasn't there for your first day of high school or your first date. I'm going to miss your first prom and your high school graduation.

There was some good that came out of you moving away. Not having you around all the time made me truly appreciate the relationship we have. Since we only spend a few weeks out of the year together, the time we do spend together is so precious. We never argue or butt heads because there's no time to. I am so grateful that we can cherish each minute we spend together because not many siblings feel that way.

Even though I can't be there every day, I will always be there when you need me because you're always there for me. I promise to be there for your bad days and your break ups, and to build you up when you're broken down. I promise to make time for you when you're in need because you always make time for me.

Thank you for answering the phone whenever I call you and listening for hours. Thank you for knowing when to offer advice and when to just let me spill my feelings. Thank you for always knowing how to make me feel better and showing that you care. Thank you for still being my rock from 500 miles away.
