Perhaps keeping busy and distracting yourself with thoughts about your ex-gf would help? It seems you only focus in your posts about her, not about you.....
How are you? Apart from anything to do with your recent break up...
How are you feeling? Physically? Emotionally? How is the battle with cravings going? When is your next appointment with your counselor, and have you been able to talk about all this with your counselor? Do you keep a journal--I found that really helpful in the past.
As someone who has lived through my own traumatic break up, keeping busy is a life-saver!
