I've had a failed marriage and hit rock bottom all at once (including 5 years in prison, kids not talking to me, etc). For the relationship part, if you had a tight friends group, they would just keep you busy until the pain turned numb. We don't have that community always and have to keep ourselves busy.

It sucks waking up to an empty home. I went from making my kids breakfast/packing lunches every morning, getting daily hugs and 'I love you dads' to this huge soul crushing void. It sucks.

Before sentenced to prison so still out in the world, but after losing wife/family/career/home I kept busy with podcasts, audiobooks, comedy records always going to fill the 'friends keeping you busy' part. Now's not the best time to spend a lot of one on one time with your inner voice, he's a smart dude but not always our personal biggest champion/hype man :)

I forced myself to maintain normal sleep patterns. If I wanted to sleep by 10 and couldn't, I either exercised more or went to bed earlier and earlier. Forced myself to maintain a healthy diet. Forced myself to exercise regularly and consistently. Those are a must. Get up the same time every day, go to sleep the same time. Plan and eat healthy meals. Have easy emergency healthy meals for when you are too depressed to cook. Have an exercise routine and if you can't sleep, up it. If you go to a gym, swim, it's such a different modality. For me I mountain biked. I mountain biked a lot. When I felt like I was going to crumble (divorce lawyer dates, court dates, realtor selling the house date, hyping myself to make my weekly phone call to each of my kids knowing that they weren't going to answer but that I still needed to keep calling) I got on that bike and road until I didn't have the energy to be anxious. But I didn't ride risky, didn't seek adrenalin because the last thing you need is to get hurt. Hmmm, looking back I also did a lot of white water rafting. Again your brain has to break it's unhealthy constant negative focuses and just focus on getting past the current rocks in front of you.

So routine, intentional (and proactive) self care, with healthy distractions to break the unhealthy focus on your current situation and giving yourself space.

You'll get through this I promise. You will be surprised in life to find out just what you can and cannot get through. Keep your head up! It's not just you, what you are going through while unique and incredibly painful to you and worth being given the weight it deserves as one of the hardest things you will go through is also something you share with the rest of us afflicted with 'the human condition'.
