There are two features of Emacs that every Emacs user should learn to
use so that the problem of "losing anything I was working on" does not
occur:

1. Emacs auto-save and recover.  When you restart Emacs, you should be
able to recover most or all of your lost work by using the
‘recover-session’ command.  This is documented in the ‘Recover’
sub-section of the ‘Auto Save’ section of the ‘Files’ chapter of the
Emacs user manual.  To read the ‘Auto Save’ section from the beginning,
you can type M-: (that is, your meta key followed by the colon key,
‘:’), and then type the following text after the ‘Eval:’ prompt:

   (info "(emacs) Auto Save")


2. Emacs desktops.  Emacs users can divide their work into sessions
(groups of files and buffers) called ‘desktops’.  These can be loaded
and switched among depending on need.  Once set up, these desktops will
automatically keep track of a set of files and buffers so that it is not
necessary for an Emacs user to open or restore the set manually using
multiple commands.  Instead, loading a ‘desktop’ will cause Emacs to
restore them for the user.  How to set up Emacs to use the ‘desktop’
feature is documented in the Emacs user manual.

  M-: (info "(emacs) Saving Emacs Sessions")

Note that it is possible to have any number of desktops and to switch
among them in a single Emacs session.  This supports working on multiple
projects and then switching among them even if many days, weeks, months,
or years have passed since you last worked on a given project (assumes
that the .emacs.desktop file for a given project has not become
incompatible with the ‘desktop’ library).
