Suggestions:
Move down in limits 'til you get your confidence back to something approaching what it was before.

Re-read books if you don't feel quite up to playing right now--the games will still be there...

Have a look back over some of your winning hands if you have stored hand histories--remind yourself how it's done, what you're waiting for (when it seems you're throwing away crap hand after crap hand). The worst thing about chasing losses is trying to 'make' it happen, and playing way too LAGgy.
