I suppose the thing is with using someone/something else for motivation, is that if circumstances change outside of our control then our motivation could change too.
Can you look at it a different way, e.g.:
I want to stay sober so that I am present in all my relationships. I want the people I love to see the best of me. Being sober helps me to be the type of person others can rely on. If I get high today then I will become unreliable, unavailable and a liability to the people who care about me. I don’t want to put them through that any more. I will feel physically ill, guilty and ashamed. I don’t want to put myself through that anymore.
Fell off the wagon again lastnight, with out sounding cringe or desperate, but not having family or support in anyway makes it harder, the cravings right now are through the roof! I don’t want to touch it, but it’s the only time I’ll feel happy. Meeeeeeh
So sorry to here your struggling I’m glad your here reaching out it goes to show u don’t really want to give in . That’s the addict lie telling u your only happy when u use … cos before long u will end up wanting more and more then your end up feeling all them horrible feeling of guilt and shame and your still be on your own feeling worse then ever … There’s so much you can do in life to make u happy… think of the reasons why u quit think of how good your feel if you go out for a walk or phone a friend in recovery and talk how your feeling through.
