Depression often accompanies the fear that grips us after our initial diagnosis. See your doctor about this, pronto!
Have you had any surgery (other than PEG insertion)? As others have said, this is not inevitably a horrible experience. Don't get me wrong, there are about a thousand things any of us would rather do, but this is very doable.
Talk to your doctor or CCC about local support groups that can provide some companionship and assistance while you go through treatment.
