When you put anything into the default sidebar, it overwrites all the widgets that were there.
To get to your dashboard, you need to add /wp-admin to the end of your blog’s URL (so, http://drugsruingoodpeople.org/wp-admin). You’ll either go straight to your dashboard, or you’ll get a log in screen (depending on your browser cache, cookies, etc). If you get the log in screen, just put in the username and password you normally use.
Once you’re logged in, to restore the log in link, etc to your sidebar, drag in the “Meta” widget. Or take all the widgets out of the sidebar to go back to the default.
