1 year today since my loss.

Today marks exactly 1 year since I woke up to cramps and my eventual loss. Is it normal to still be feeling so sad? I was only 5 weeks along, no body understands why I'm still so upset about it. My partner never speaks about it, he put on the brace no emotions thing  when it happened and only speaks about it if I push him. He has said all along "it's like it was there and then it wasn't, I didn't know how to feel about it at all" which is understandable. But I'm still heart broken.
