Bridget, if you were my daughter, I would be so proud of you I would be telling everybody I met. what a shame your mother is so brainwashed by this religion that she shuns you. The fact that you have done so well in life is amazing in of itself, but even more so when you consider that you had no help or support from your own mother. I hope you sent this to her so she can see what she missed out on.
Don't worry about shunning any children you may have - you would never do that, knowing how hurtful it is. You might want to consider adoption, or foster care, you and your husband would make wonderful parents, I'm sure.
As for your occasional insomnia, I always keep Benedryl on hand, it's safe and not habit forming. My doctor says it is safe to use. Getting a good night's sleep is so important, I can't function if I don't get my Zs, and it seems the older I get, the harder it is to get a good night's sleep.
