Welcome to our family. Many of us can relate to your story as we've been through the same thing. Many of us have also dealt with the depression. Believe it or not, depression is one of the symptoms of this disease. So, do not beat yourself up about this. Having a chronic illness will make most of us depressed. You have lost your good health and your way of life has been changed. It is quite understandable.
I have always advocated that it is equally important for us to treat our mental health as it is to treat our physical health. One cannot get better without the other. So, perhaps you can find someone to help you in this area; your faith adviser, a therapist, a close family member etc.
Of course, you can always come here to talk to us. This site is filled with people who truly understand and who want to help you in any way that we can. You will find that there is always someone here when you need us! I wish you the very best.
Peace and Blessings
Look For The Good and Praise It!
