LOL there is more to anxiety than washing your face and telling an anxiety sufferer to get a good sleep isn't helpful, if they could sleep properly (neither too little nor too much) they probably will be functioning well anyway.

Get a good relaxation track (I don't mean just quiet music I mean one produced professionally by a clinical hypnotherapist - there a a few on line, I have some I have produced myself, They will be the first step then get a good anxiety program which explains whats going on in your mind and what you can do about it - because you can kick this with the right advice. Avoid persription drugs unless your anxiety is at panic attack levels of you have sunk into dpression then get off them as fast as you can.
