Good Morning, this is Kitt. Many people with chronic illness have anxiety and depression and it is nothing to feel ashamed of. I would like to suggest that you are up front with your physician and talk with him /her about your feelings.
You are normal like millions of others that have depression and if you can receive help with your depression than by all means talk to your Doctor. You are not twisted at all, you are human.
You are always welcome to come here and talk with the other members who are going through the same thing you are.
Gentle Hugs to you.
I bumped up a thread on depression from back in February that you might find helpful.
