yup i went through this many times, where i would stop for 2/3 week get so down and lonely and depressed etc, then after many years drinking i sought outside help in the form of a counseller who determined i had clinical depression and anxiety and all this time i had been going back to drinking to try and self medicate...cant believe i never saw that one coming...oh well am sober now so alls well! hope you feel better soon:-)
