There are many different consecrations.  Here are  a small sample:

Consecration of your death :

a beautiful consecration by Mark Mallet - see below (keep scrolling down) - video and wording

Consecration of our death


Go into video at about 20.25 mins in if you don't wish to watch it all - look at the emotion from Mark as he reads the below words - beautiful for people who wish to consecrate their death to the Lord.  May be done at any time (ie when you are well / when you are not)
