Not3late, you need a better plan, my friend. White knuckling it is not going to work in the long term.
It's not about will power, it's about asking for help and getting support.
Do you have any f to f support such as AA ?
You need to find a way that works for you, what will do next time if you get agitiated ? How will you deal with the cravings ?
Stay close, I practically live here at the moment, it's mostly what's kept me going. xx
