Can you take her to a private psychologist or psychiatrist? I know it might be pricey but it would be worth it to find out what's wrong! I would certainly do it or anything else I could to figure out what was going on. Maybe one of them can test her and see if they can determine if she has a problem of some sort.
I'd give it a try.

I'm glad you updated us 1tash1. I've thought of you many times since your last post. Thanks for letting us know what's going on.

Take care and keep us updated, ok? You're part of our "family" here. God bless & talk to you soon. Hugs, Lee
