How do YOU FEEL about going or not going? Is being there important to you for whatever reason? Or, is going problematic?
Also, as a single person, i feel that social requirements like this are more difficult for us. We just dont have the built-in support and resources. For instance, for my uncle's funeral recently when the weather was always below ten degrees, i didnt have dependable transportation, where a family might have two cars and take the better one. And if the wife is too upset, the husband can drive. Etc.
Otoh, i traveled almost all day to attend a cousin's service. He was single, and i just wanted to be there.
So think about what you really want. Dont worry about other peoples expectations. Maybe talk to people ahead of time and see if it does still seem too messed up there to go back, or if there is someone you can connect with? And im sorry for your loss
