Sorry to hear about your loss,

Even being in nature have a stroll for a bit for e.g can help you to clear your thoughts, effectively so you think with more clarity too,
You will find surprising unexpected profound inspiration for your loved ones funeral such as favourites poems, songs flowers , eulogy ect.
Obviously if you don't feel up to this in regard of Eulogy , a relative or a friend could do this for you,
The funeral director can Obviously can and will do this for you too, reading out Eulogy,
The religious faith person or Celebant or Humanist Can do this aswell.
