I'm sorry. I missed my grandmother's funeral mostly because of the weather; but it was also just a hard one to deal with. They didn't have streaming ones back then.
Maybe sometime soon you will feel like doing a little something on your own. I do find it helpful for me; some little act of remembrance. I have an angel holding a cardinal (her favorite bird) for my garden. I've found it helpful to do something at some point. It could even be painting rocks to leave along a trail or just lighting a candle while you think of about her and/or talk to her.
