How can I say goodbye after her death?

Hi ..can anyone offer me any advice???
I am a teen whose Grandma died a couple of years back and I still haven't been able to move on or come to terms with it
I need help on a few questions...can anyone provide me with any answers?????
.
. I need to know................. how can i say Goodbye to her . I never got a chance to speak to her before she died and i wasn't allowed to go to her funeral. I still feel like i desperately need to say goodbye to her? How can i do this? Do you have any suggestions? It's just I want to go to the crematorium to say goodbye to her and to say goodbye out loud by speaking or reading a letter or poem or something. BUT IS THIS SOMETHING THAT A LOT OF PEOPLE DO...OR IS IT NOT?? PLEASE BE HONEST.IF IT IS NOT USUAL THEN I WOULD RATHER FIND AN ALTERNATIVE METHOD OF SAYING GOODBYE.
:( DOES ANYONE OUT THERE have any other ideas as to how I can say goodbye to her.

The funeral is a way of saying good bye. I wish you had been allowed to attend it. It is a good idea to go to the crematorium or her grave to say good buy to her. Reading a letter or a poem is very nice and you can do it loudly.
