You are going to cycle through the "stages of grief" many times as you process everything, comes to terms with the reality of it all. Just accept the feelings are real, sit with them awhile, then let them go. Then you'll hit another round, a little deeper or different take on those feelings, and each time the cycle will be shorter and less intense, usually.
It's normal to miss her, there are triggers everywhere. And the loneliness is normal too. It'll hit you from out of nowhere. Be okay with it. It'll pass. I promise.
Be gentle with yourself, it's okay to take some "down time", you NEED to, to recharge for the stuff ahead.
Soon you will be looking forward to your new life with more excitement than looking back at the past, it's pain, and also those good times.
Well, that is how it's been for me, at least...
Hang in there!
