Like so many others, I'm hoping you can hang in there and get this sorted out. This is always a tough time of year, 27 years of military never made me as miserable as one ex-wife. When things really sucked, I picked up a shift working the door to a bar on Christmas Eve. If you want to see some truly miserable people go to a bar on Christmas eve and wait to see what's left after the after work crowd heads home.
We had one miserable bastard walking around the joint whining to anyone who would listen and failing to see that they were all as miserable as him. Finally, as I walked him to the door, he turned and yelled, "If there was a bridge near here, I'd jump off it!" As one, the dozen or so patrons turned and yelled, "Six blocks down take a fucking right!!!!!" I was both appalled and impressed. They all knew where to go, sadly.
That being said, I worked through my misery and got this miserable bitch sorted and out of my life once and for all. I gave up that part time job and do not hang out in bars anymore. I'm not religious but I picked up one of those daily prayer pocket calendars from the free shit table at a local church and kept it in my lunch box for most of the next year. Having a positive though to ponder daily helped me grind thru my misery. I've had misery in my life that has made me want to sit down and die, very little of it was related to my military career. My war zone adventures tended to be endless hours of work and people dropping rockets and mortars on my location in a vague sort of way.
I won't bore you with stupid sayings or shit from a plaque in some idiot's office but there is one that pretty much summed up the miserable parts of life and how I resolved them.
What is the best way to eat a shit sandwich? One bite at a time.
Find discreet help that will not ruin your life and get it sorted. Take a few minutes and look at the good things before you let the bad things win. You have a wife who hopefully loves you. You have dozens of random assholes on a random shooting website that hope you get this resolved.
This is the darkest, coldest time of the year and that has an effect on people's mental health. Turn on more lights in your house and brighten up the place, it honest to God helps some people. So does going to bed and waking up at regular hours.
Until you find the right group or person to help you, do what you can to help yourself.
