Haywire - I think that what you most need right now is practical assistance along the lines of mummytime's comment.
While I agree with Offred a lot, I also think there's a point past which trying to shake you out of this is not going to help. Trying to convince you that you are seeing things from a particular angle isn't going to help.
Practical does help, though.
A few years ago, I had a total breakdown, and when I look back at it with some perspective, the biggest gift my then-husband gave me was his total and utter inability to help or support me. In that moment when I realised that it wasn't fair and my world came crashing down around me, something became totally, crystal clear:
I was the only person who was going to get me out of this shit.
Not fair, not my fault, definitely not what I wanted. But, that rock-bottom realisation was enough for me to start getting help: regular counselling (yes, it's hard; yes, it gets better), regular exercise, and - you might not want to hear this - the dismantling of most of my life, from my marriage, to my home, to my job, to my relationships with my family (some of which got stronger as a result).
Just my 2c.
You might be the only person who can help you. I hope you do.
