Firstly I wanted to thank everyone for their thoughts and prayers and messages. My sister's surgery was 2 1/2 hours, 4 hours of recovery and we saw her after and she looks good. I am so unbelievably relieved I can't tell you.
As much as I tried to keep my thoughts positive and push down the panic, the past couple of days was really hard to fight the fear. Both my parents are gone. I'm not close to my brother; his son has disowned the family, his daughter I see one or twice a year. My sister's kids are great but we're not particularly close. I haven't seen her son in about 3 or 4 years; her daughter is closest. I just couldn't bear to lose someone else.
There's always a risk, even with a healthy person, when they go under general anaesthetic; my sister was at high risk.
She's not completely out of the woods yet but I'm sure everything will be fine.
I feel like I can breathe again.
So thank you all for your support. It means a lot :)
