Missing him 😖

I miss my hubby so much. He left for marine boot camp yesterday... He's gonna be gone for 3 months. I'm almost due & he has to miss the birth... I can't sleep because he's not sleeping in the same bed with me. It was his first day of training today & I can only write to him. I hate not being able to hear his voice or see his face. Does anyone know what could make me sleep & get my mind off of him for a bit? 😓😞
