feeling desperate

I have been NC for 6 days now, which isnt much, but is an eternity for me. i have been having very strong urges and cravings to contact him, in my head thinking of what i can possibly say to him just to get a reaction out of him... especially because i have been ignored and discarded and have a strong abandonment issue... i have been able to refrain, but its so, so hard.

the last time we spoke was last week, and we were supposed to get together, and right before it was the time we were supposed to meet up, we had a text conversation that basically ended in him saying he "didnt know if he wanted to see me anymore" (a common occurance to build me up, get my hopes up, and pull the rug out from under me) then when i gave in and fed into it by telling him off, he ignored me. i then told him to stay out of my life. for the first few days i felt good, i felt strong, but of course, that wore away and now i am fighting emotionally crippling cravings, which even feel physically painful at times.

i keep trying to say to myself over and over "youre doing great, you can do this" until the urge goes... but alas, it always comes back.

i know this probably has been asked a million times, but NC is the hardest part of this recovery process for me... can anyone give me any tips on what they do when they get a craving?

thanks so much.
