Hi Longtire:
How do I get un-crazy?
When you find out, please let me know.
This situation is similar to your past. You felt unloved, overwhelmed and alone. You married a woman and feel unloved, overwhelmed and alone. Right?
No wonder the wounds of the past are opening up and driving you batty!
The thing is Longtire, you survived the past. You grew up. You're not batty (completely, yet

, just kidding), and....you're actually wayyyy ahead of where you were because you are able to see things from an adult perspective (which as a child, would have been impossible), right?
What if you ARE accurate and not crazy after all?? Your feelings are telling you that you are not loved. The thoughts of changing the situation are many and overwhelming but you can live through it! Maybe you're afraid that you'll be MORE alone when you go?
I thought that too. From my experience, I was pleasantly surprised. I was greatly relieved when my X finally left. I asked him to leave, so it is a different situation, but I felt much like you....unloved, overwhelmed and alone. It was such a relief not to have to deal with him any more. Not to have to shovel his junk away from me all the time.
I stayed in the matrimonial home and there were a lot of memories and it was hard. I would have moved, in a minute but I stayed there for the kids. I wanted their lives disrupted as little as possible. They lost their parents, as a unit, but at least they didn't lose their home, their friends, their school, their neighbourhood, etc. I was lucky that my X was reasonable enough to work things out with but I gotta say....it felt very empty when he left (even though we were all miserable when he was there).
Maybe we even miss misery when it leaves because it's such a drastic change??
Anyway......I understand your frustration and fears about looking for a place. Here's what helps me (part of my decision making formula):
1. Think of the worst possible thing that can happen.
2. Accept it.
3. Make a plan for it.
4. And forget it because the chances of the worst possible thing happening are just about zilch.
Still.....at least if you think of the worst and it happens, at least you'll have thought about it once before and have a plan for it.
!. So.......you find a place and the worst thing that could happen is that you hate it, can't stand it, are totally unhappy there, right?
2. Fine. Decide now that you won't die if that happens. After all, it's just a place and it doesn't have to be permanent, does it? So ok, you can live in this not so great place, if you have to, because you know it won't last forever and because you know it will get you away from a relationship in which you feel unloved, overwhelmed and alone. At least it will be your own place and you won't have to be in such a relationship any more.
3. The plan. You can simply keep looking for a better place, after that. In the mean time, you can make that not so great place as comfy and homey as possible. You can focus on other things in your life besides the place in which you live. You can go out more and become a social butterfly. You can join activities and spend more time living than worrying about where you lay your head at night. You can easily live through such a not so great place. You don't HAVE to hate it and you can find a better place.
4. Forget it all because the chances are much higher that you will find a fairly nice place, or at least, an ok place and be content.
Best of luck, Longtire. Glad you're seeing your new counsellor soon and hope you will get to a GP and get a sleep med because (sorry forgot who said it....but they're right...)....you need your sleep to function at your peek and to avoid potentially feeling worse.
