It sounds as though youre doing the right thing seeking medical support. After you’ve dealt with the physical withdrawals, I’d probably suggest that you begin to explore the driving forces behind why you used in the first instance and what triggers the depressive episodes. If it is caused by bodily pain then perhaps discuss this with your doctor, maybe pain management is what you might need.
You could also suggest counselling for you both, If you are both willing that is. Perhaps she needs some space right now – I’m sure lockdown doesn’t help. She may need to process everything that’s been learnt recently. It’s not easy to understand the lies when it comes to addiction, it’s still Betrayal and us humans, especially close loved ones don’t like that. Partly I think because our partners are meant to be the people we turn to – when that doesn’t happen I think we start to question things like trust, understanding and togetherness.
Best of luck
