Bad news from "back home"

I just got back from a holiday in the UK the night before last, I was there for my sister's wedding but there were added emotions because my cousin was in a coma so there were empty seats, she and her parents, partner and brothers were all sorely missed and the day was bittersweet. Yesterday afternoon my cousin died. My head is all over the place at the moment and exacerbated by not sleeping or eating properly in the UK (I tried to pack too much in to a week) My mum is having a really rough time and walked out of her job on impulse yesterday just before we all found out (this is really not like her) I don't know if I feel like I should go back to be with them but to be honest last week with the tension of everyone knowing this would happen soon but just not when it would happen, I found so hard, I just wanted to retreat and was so relieved to come home. I didn't spend any quality time with my sister before the wedding like we'd planned to, we tried but we spent half of it crying together and now she's on her honeymoon and we've decided not to tell her til she gets back. It's her husband's birthday today and I just sent him a chirpy message on facebook so they won't suspect something is up. Sorry for the state of this post, my brain feels as scrambled as this post probably looks. Not even sure what I expect anyone to say in reply I just want to get off my chest. Maybe advice about whether to go back to the UK or not, would be useful.
