Welcome sunshine. It's natural to feel this way. When I was first diagnosed I was pissed. I had a tough childhood and felt I had "paid my dues" and didn't deserve it. Unfortunately life doesn't work that way and I found speaking to a therapist helped me work through those feelings.

A person can't be forced to understand or empathize and I hope your parents decide to educate themselves on the illness. Perhaps asking your parents to attend one of your pdoc appointments would help? If they show that they're not willing to be supportive etc. there's no point beating your head against a brick wall. You need to take care of yourself and ensure you build up a healthy support system.

The book in my signature is for family members/spouses of those diagnosed. Perhaps your parents would be willing to read it.
