Don’t get too disheartened by this minor setback. We have all been there and relaspse is most common during the first 2 years getting clean. Being away from a toxic relationship is probably for the best. I was in one and it was so one sided that when I was finally free the relief was incredible. As for rest take it a day at a time and things get easier.
I have been clean since December 27th 2019 and I still have bad days where all I want is to use. Whenever I get like this I call somebody just to hear a voice and have a normal conversation or i find any other activity I can do to occupy myself and alleviate the desire to get wasted.
Keep going.
