It's OK to grieve. Cry all you have to and go right ahead and feel sad. They're your feelings and you need to honor them.
Don't put any extra stress on yourself by "trying" to move on. Everyone grieves different. Of course you hurt right now. You'll move on when you're ready.
The time to reflect on all the happy times will come.
I understand you are sad and I'm sorry you're hurting.
