Confused :/

Hi everyone...
I have no text with me this time but just a question... Have you ever be so confused that you don't even know how to deal with anything ? Has someone randomly make you feel like that?
Losing all your bearings, just because of single sentence? That sentence that destroys all the feelings and beliefs you could have had.
And then you just dont know what to do, you don't know what to say, and you don't know what to think...
I just don't know how to get over that confusion and how to deal with it :/
I'm lost
