Hard to move on

Why is it so hard to move on from something? WHY can't I let go? I hate being depressed. It hurts. It's like there's a hole in my heart, and no matter what I do, or how hard I try, that hole can't be filled. The pain is excrutiating. It goes away for a while......when I'm with friends, but even they can't keep the nightmares away. I wish I could forget, but I don't want to at the same time. It's funny how even after someone breaks your heart like it's made of glass, you can still love them with all the shattered little pieces. Broken hearts.........suck. I just need some prayers and a  hug......a lot of prayers.....and hugs :/
