Feeling overwhelmed

Last night, I went to bed feeling like this.  I am having to change cards at my bank because mine may have been compromised.  That means I'm dealing with a bunch of paperwork and confusing stuff.  So I went to the office and got help, trying to do it all online with email and faxes because I no longer have a car and don't drive ... sigh.  So is my Wednesday Word "sigh"?  Or "overwhelmed"?  Or "frustrated"?  I guess I don't need to define any of these for you, right?  Does anyone else feel like saying one of those words, too?
