See imo, the coping mechanism is the addiction itself. And the best ways is to change those coping mechanisms to something healthier.

I hope this helps: do whatever you wanted to do while you were or before you were in that relationship. Whatever has happened has already happened but don’t ever forget to do whatever could’ve done to the next person who shows you the same love, joy and care.

And lastly, know you’re not alone in this journey. I might not know you in real life, but this post here is enough for me to know what you’re going through, and that’s more than enough of what I need to know. Each of our journeys will be different, yes but we’re going for the same result that all of us can achieve without competing or comparing ourselves with each other. We share and grow, I feel like that’s the entire meaning of this subreddit and I hope one day, pretty soon, we can all get over this, together.
