Hi Polly. Welcome to the forum. I am so sorry to hear of your loss.
It does help to get your feelings out, whether that be talkin or writing them down, rather than keep them running amok in your head. Somehow it helps us to organise and make sense of the many different things that swirl around our minds.
There is no normal for grief. No two people grieve the same, even if it's for the same person. There are common experiences but we all do it differently and at different timescales. Be assured that what you are feeling is perfectly normal for you.
Wishing you strength.
