Some suggestions for writing a Eulogy would be, to ask the family who will be talking, will it be one or more people, what topic are those people covering about the deceased, making sure not to cover the same topics, and find out how long you will be talking for.

The first suggestion would be to put pen to paper and, in no order, write things that come to your mind and things you may wish to say.  Then you may wish to take a break and review your notes before constructing them as your eulogy.

Do not be afraid to ask for help from family or friends, they may even remind you of certain events that you have missed.

If you give some notice to your minister/ celebrant that you may not feel up to speaking on the day they may on your behalf read your eulogy for you providing you hand them a legible copy beforehand.
