The space is most likely being occupied by the various files and folders in ~/Library, which is hidden by default on OS X. You can show the Library folder by navigating to your home folder in Finder, pressing ⌘J and showing the Library folder.

Furthermore, you can run the following command in your home folder which will list all the files and folders in your home folder, including hidden files and folders, and display their sizes.

du -shc .??* *

As for the massive file size in ~/Library/Application Support, you have to figure out which apps taking up the largest space. Run these apps and try to reset the caches with the built-in options or menus. If you still can’t find one, consider remove the largest file (not entire folder).

Take time to skim through the list and delete folder where apps are no longer installed (usually they’re named after the app name). It’s possible that you didn’t remove apps correctly before.

I was having a similar issue. I had over 60 GB of "movies" that I couldn't find anywhere. It was actually in my recently deleted album of my photos.
