You will make it... you'll have to find what works for you. Keep breathing, keep busy. Don't brood and get in a rut. Journal your feelings, write them down, punch a pillow. Cry in the shower to get it all out. But get up and moving, use this time to prepare for when you can speak to him next. Work out, run, do yoga, heck, volunteer with some veterans. Don't dwell, use your freak out energy is better ways.
Hang in there.
