It's rough. I hate going home because we just bought the house and accomplished a big goal we had. It's a different kind of quiet that I've never experienced before.
It just takes time and a lot of it to find a new routine but you will.
Everything you are feeling is normal. I'm told it's similar to coming off drugs because the chemicals in the brain are so messed up.
Just take a deep breathe and allow yourself to feel everything. It's the only way through it. The pain will subside and then it will knock you to your knees again.
I struggle with constant reminders too... Songs, places, memories, text messages, inside jokes. It's brutal.
