Can't sleep

It's 3am and I've been listening to songs and analysing the lyrics to "So you can cry" by Ne-yo and "Don't Love You No More" by Craig David, as if that's going to help me sleep. I love those songs but I guess they are quite depressing in their own right and unfortunately that doesn't help with my mood.
Have you ever as a kid gone, "I'm gonna run away and I'm never coming back!" But in the end, you end up camping in your room or hiding somewhere in the house and just change your mind and reappear by morning? I was thinking to myself that I'd like to do that. Just pack my bags and leave for somewhere away from family, friends and workmates. Disappear off the radar for a while. It's a crazy thought but it would be nice. I haven't had some ME time in a while (disregarding the night that me and my fiance had a fight because I wasn't in a warm comfy place).
I think I've been rushing around between people too much lately that I guess I've neglected myself. I gotta take a siesta.
