It sounds like you should go.

Falling apart - you should possibly do it in moderation.

At my father's funeral, my siblings and I sort of were all lined up - my sister was crying so, my brother had his arm around her - one of my sister's coworkers ran up - shoved my brother out of the way and held my sister and bawled with her.

While it was probably great for my sister, the rest of us were fairly boggled since we knew that that coworker had never even met our father and the bawling seemed a bit overdone given that.
