How do you determine that swap is not being used?  Have you run top (for
example) to see cpu and memory usage?

Files downloaded by apt go to /var/cache/apt/archives.  You can run the
apt-get clean command to delete them.  If your home directory is a
separate partition, this will not help your problem.

Have you attempted to find out which directories under your /home are
taking up all this space?

$ du -s ~/.* ~/* | sort -k1 -n

This command will show you usage of all files/directories in your home
directory.  Look at the last few lines in the output for anything that
is taking up unusual amounts of space.

Nothing so far seems like it could be caused by filesystem
