When will it get easier, how to get through the nights.

Its been a week now, it hurts, it feels hollow, not all the time. Most of the day I can get by almost fine. But as the night approaches the feels fester, till I feel pukish and feel like I am struggling to breathe, the only thing that seems to help is talking to friends, and letting out my emotions with them, I dont wanna feel this was anymore.
