As others have mentioned, you are arguably not as close to rock bottom as one can be. I hit rock bottom when I lost my home, my job, my ability to walk, was on assistance and bought my groceries with food stamps. How I got to rock bottom is a story for a meeting.
I found solace in recovery. Recovery is different for everyone as is rock bottom. Therefore if you feel you've lost more than you were willing to and you're at a precipice of a major life change that will bring you up out from the bottom, or you'll find rock bottom can even be lower than your realize. Again, what that means is going to be different for everyone, but if you have a need that you must change something in order to be better, then you already know what to do. Obviously if you're addicted to heroin, that change would be sobriety and recovery.
I'm not trying to give you answers as those are things you're going to have to figure out for yourself.
You've been around for three decades and been adulting for less than one. You've got at least 4 more decades to define yourself and your life. The best part is, you are the director, producer and actor in how that future pans out.
