Suffering from anxiety and depression are really going to make quitting tougher than it already is, which is already pretty tough. Your addiction likes to whisper in your ear whenever and wherever you are vulnerable, in your case you will no doubt tell yourself that you will have to dip again to moderate your mood. You're going to have to do your best to recognize that siren song for what it is....true and utter bullshit. Dipping does not make you happier. But believe me when I tell you, that quitting ultimately will. Your addiction just wants its fix and it will do anything to get it, included messing with your head when you are already fragile. Others in your shoes have done this...so can you. Be strong...good luck!!! And have a Happy Easter.
