How do I cope after my dog was put down due to aggression?

I must clarify this dog belonged to my brother and his girlfriend. It was their decision and I disagree with it. I am 20 years old and well aware of the circumstances surrounding their choice. But it was not what I would have done.

Zara was a mix of a collie and labrador. Absolutely lovely dog and always made my day. However, she was always afraid of people. As a pup she used to back away from them. But as she got older she began barking and then lunging. After she tried to bite a friend of my brother’s, my family discussed it and decided it was the safest thing to do as there are many children in the area and it is impossible to keep an eye on her at all times. I was told yesterday evening about the decision and 24 hours later she is gone. I said my goodbyes and I am thankful for that. However, I became so close to the dog I feel quite empty inside knowing that she is gone. I feel I have let her down.
As I have said the decision was not mine and I disagreed with it. I know the reasons behind the decision were valid. I just can’t cope with the fact she is gone. Is there any way to cope with this? Thank you
Also to clarify she has lunged at several people before we have intervened. It was only a matter of time before it happened when nobody was around.
We took her to several behaviour specialists and classes. Nothing was working. This was recommended to us by the local vet.
