Hey PE.... This is what also happened to me, a born-in 5th generation very visible elder. In 2010 after I turned 50, my then wife and I started a fade. We were scared to lose our children and grandchildren to shunning. Then my wife left me. So, my business was in a decline, my religion was a joke, my 30 year marriage failed, and I risked loosing my kids. I felt so lonely always even though I was never DFd. My parents and extended family ignore me.
I hated it when people told me that "time will heal", but, it is true. I figured that Dr Time must be a quack. A cut on your arm is easy to monitor as it heals, but our emotions and brains are harder to monitor through the healing process, and can be full of ups and downs. It is like loosing weight. Years of junk food don't disappear in a week. The desire to go back to junk food is often strong, but exercise and good foods eventually change you and you can reach your goal.
My passion was my grandkids. But also, I read science, (hi cofty), history, took classes at community college, joined a few Meetup.com groups. I remember the day near Bishop, California when I hiked through the 4700 year old Bristlecone Pines at 11000 ft elevation growing out of white rocks that used to be a limestone seabed and proving to myself that no flood waters covered it 4600 years ago. I promise you that at 31, it will likely be worth it. I got my kids out when they were early 30's and we are a happy group of xjw's with new productive ways of life. I occasionally have some strange dream like giving a talk at the assembly and I can't find my notes. But JW influence is 90% gone. Be patient with yourself and understand that you have some damage. It will likely turn out better for you and your daughter someday if you stand for what is right.
Also, a friendly wave to you single ladies out there:)
