I am very sorry to hear about your diagnosis, and what makes me even sadder is that nobody became aware of your condition when you were a child.
You missed out on things that are normal for other children, and so part of your adult life was difficult as well.
Your sister and your brother-n-law helped you a great deal, and now you are getting even more help, and I'm glad that you have your precious girl Heidi to comfort you.
I wish you the very best for the future.
