YOU ARE A FRIGGIN SAINT!!!
I read it, all of it, and I still can't fathom how you managed to live it!!!
I too suffer from bouts of psychosis during severe depressions, so please don't think you're alone on that front, its not as uncommon as the research tends to show.
FWIW, I believe your wife's abuse exacerbated your BP, stressful situations are known to either trigger or amplify episodes.
With that being said, I'm SO PROUD OF YOU, seriously, I know I don't know you from a bar of soap, but I honestly am so proud of how far you've managed to come. Mostly, I'm proud of you for seeing your wife for who and what she is AND knowing you deserve better. I'm proud of you for taking the necessary steps to rid your life of her toxicity.
You, deserve sainthood, a medal and bloody hell, they may as well throw in a statue too!!!
