I'm so sorry to hear about your loss, this must be so difficult for you as it seems to have been really sudden and unexpected. There must be so much going through your mind right now, we are all here to listen or you could use live help if you think that would be useful. There is an information booklet you can download
here it begins with more practical matters which probably aren't relevant to you, but you might find the information on grieving helpful.
You can confide in us, but I can understand that it would be more helpful to have someone 'physically' be there for you. Are there any of your friends or family who you might be able to talk to? Getting through this initial shock will probably be the most difficult part for you, and it can be really helpful to even just have one person who you can go to for support. There are also helplines you can phone if you are able to do that.
I hope that it helped a little to write this down, please keep talking to us. Get in touch any time, i'm thinking about you. Take care. xxx
