When you have to depart from this world and have to meet death (eventually), then why wish delay? (i.e., why feel nervous about death?)

The best form of devotion to the service of God is not to make a show of it.

Take warning! He has not exposed so many of your sinful activities that it appears as if He has forgiven you (it may be that He has given you time to repent).

When you get ill do not get nervous about it and try as much as possible to be hopeful.
