Catkins I found the six months after harder emotionally than the six weeks after. It's because time has lapsed and you've had more time to think and reflect and feel your emotions. Mixed emotions of sadness, regret, love, emptiness, memories, even guilt will come over you and its all normal to the process of grieving.
And as time passes it will become easier to accept these thoughts and feelings as you get on with your own life which is what you are supposed to do. x
