I don’t like how women tell men to go to talk-therapy, and I think you’ve mentioned that you’ve gone, but if you haven’t… well, go. Also, look for a male therapist.
As for therapy, I am a huge proponent of action therapy, ie: doing something rather than talking about doing something. So what are you doing to take care of your physical body? Yoga was huge for me in processing my divorce. I did a very demanding series, but it’s not for everyone. A martial art might work. Or walk, or swim. Anything physical, wear yourself out, in a healthy way, it’ll help.
And yes, you probably already know you should look for another job and stop drinking.
I resisted change when my marriage ended, but I ended up doing a lot of different things, things that forced me to do something completely different and get out of my comfort zone. There was yoga, a career change, and a number of different activities. It felt brutal at times, but I came out on the other end feeling much better about myself.
As for your writing? I emailed you. I’ve love to add a couple of your old articles to my publication on Medium called Animated Man. I appreciate the journey you’re on.
