So sad and lost

Hi I lost my mum 2 weeks ago to cancer. She was having treatment which was working but then it came up everywhere. She was diagnosed at Christmas 2016. Mum deteriorated in a week so I keep thinking at least she wasn't suffering for too long. I just miss her so much I was very close to mum, and I'm worrying about the funeral next week, just don't know how I'm going to get through it. I do have lots of family though x
