Jeez, Im not even sure if the title is correct/makes sense 
I have 2 nieces, and 2 nephews by my sister
I love them as much as I love my own children,
Extremely close family, all live within 3 minute walk from each other, see all daily, have my nieces and nephews over night regularly, my children are the same age, are in same school, even in same classes
Yesterday [tear coming thinking of it]
All my family [20 of us] went to a zoo day out.
About 3ish, youngest nephew fell off a climbing frame, he grazed his fingers quite badly. Sister scooped him up/cuddled, said he was also tired. Gave him drink, walked him in buggy.Sister suggested something was not right perhaps he had broken finger or something. By the way he was holding them/bending etc, I could tell he had not. So ease her mind, and she agreed he was tired, and perhaps a sleep would be good for him [about 30 mins after accident, he did not bang his head either]
He went to sleep lovely, and we all agreed he had been tired afterall.
He woke up a little bit grumpy as usual [tends to be grumpy for 10-15mins of waking up], half an hour later he was on the rides, cars, on the diggers.
He went to run off from the play area, so sisters DH grabbed his wrist [gently] and he winced a little. It hit me seeing his face, it was his arm hurting, not the cuts on his fingers [he had a long sleeve top on] I pulled his sleeve up, he had a lump on his wrist, no bruise, but his lack of using his arm, made it clear, he had broken it 
So we went around a zoo, on rides, eating, and laughing for 3 hours, all while he had a broken arm. All on my say-so/he is fine, his fingers are not broken/stupidly did not check his arm/pull up his sleeve
He had an operation this morning, because is was a bad break 
I feel bloody awful, I feel so ashamed, seen his at hospital last night, he was in so much pain.
Guilty is not the word for how I feel, while we were all enjoying ourselves, that little boy was in agony, and I made the decision it was nothing serious
Thinking about him, Im balling
Last night I was balling, I can not stop balling
Not even sure why Im typing this, its as if I want you all to type you should be ashamed of yourself, disgrace, a disgusting auntie
This has ruined me inside
