Sooooo she probably has abandonment issues....

I cannot even attempt to relate to her injury, but I can relate to her abandonment issues. I know this sounds backwards but sometimes when we're faced with difficulty it does feel comfortable to withdraw in an attempt to protect ourselves from the fear your spouse will abandon you.

She may feel like she's lost everything again, and she may be preparing to lose you, too.

I was diagnosed with a semi-rare brain and eye condition a few years ago and it still haunts me. I fear my recent headaches are from my condition worsening again and if it does I may go blind or worse. I had a breakdown a few weeks ago because I was so terrified my spouse would leave me if I went blind....he finally got me to talk about it and clarified that if I went blind I'd still be his favorite, and even if I needed his constant attention he would relocate to work from home and KILL IT. I knew it already, but it's still such a terrifying thought that I do hyperfocus on it.

If therapy isn't what she thinks she needs, getting her around other people in her situation that are making the best of what they've got can help show her that she's still the person she was, she's still independent, she's still loved and interesting and all the things you love her for. It may help
