Away from SO I can't sleep. HELP!

Alexis • Mom of a little girl ❤️ Aubree Elizabeth Dellinger was born 9/1/28
I'm away for the night helping my mom in the morning at her work. I can't sleep. I'm not by my SO. I live with him, we sleep in the same bed. I miss him horribly. I want some sleep. Anyone help me on this? Does it happen to anyone else when they are away from their SO?
