you arent a looser. The addict mind, the disease we all have, will invent any reason at all to keep you addicted. It has too, because actually there is no logical rational reason to carry on. So your disease mind will fill you with thoughts like 'i'm doomed to be an addict', 'i need to keep on using to cope with the anxiety', 'i cant quit, its too hard'. Just recognise that these thoughts are themselves part of the illness, may make them easier to deal with.
I suffered with terrible anxiety, but bizarrely, these became alot better after I stopped using. I've found that alcohol was responsible for many of the unpleasant symptoms, psychological and physical, which I was using as an excuse to continue drinking in the 1st place! I just made the decision to let go of it all.
