I haven’t much in the past, before recovery. In my recovery, yes I have. I achieve it by working the steps of my program. Personally I have chosen a twelve-step program, and the psychology of it - the daily meditation, the meetings and friends and community and mutual support, the psychological work involved in making progress through the steps (for me I find step 4 especially valuable; I do some of that reflection in my journaling almost daily) - all that psychological effort pays off with resilience that I’ve developed over time. I am not alone and I will never be alone interpersonally or, more deeply, in my mind and heart.
I can’t plan this. I look at it more like exercise. If I’m going to climb a mountain or do an extended hiking trip, or if I’m going to scale the stairs in a tall building, I have to train. That training helps me prepare for the climb, but it has other effects too, based on choices I make as part of the training: it improves my diet and my body strength and resilience; it improves my psychological state of mind.
24 hours. It’s always 24 hours. I never plan any recovery stuff more than 24 hours. That’s the horizon of my existence: what am I doing today? 
I have Zoom meetings programmed in my calendar on my phone - 3 meetings most days; 4 meetings some days - so I am never farther than a couple of hours from getting myself to a meeting to recharge my batteries. (I don’t attend every single meeting on my calendar, but I have the Zoom codes there every day so I can get to a meeting quickly and find time for it regularly, sometimes daily.) That interpersonal experience makes me feel very seen and helps me see that my addiction is nothing compared to the good feeling I get from connecting with other humans.
There are many good resources in the thread Sassy prepared here:
I know it’s hard and it seems overwhelming. Remember you’re not alone and you have support you can find. In addition to recovery programs, maybe you can also visit your doctor and get your doctor’s opinion about whether there may be some physical or psychiatric elements to this too? (In my case I get treatment for my ADHD and my depression, and take medications for both, as prescribed by my doctor. I have also worked my recovery, which improves how those medications work. It has made a huge difference in my recovery.)
