I diagnose myself because I don't open up to doctor's or therapists about my thoughts. I don't accept them as hallucinations, they're very organized and explainable, but the normal world would label it schizophrenia. My behavior fits it too, I think. I know I react to my thoughts in ways others wouldn't which is a delusion. But again, I was reacting based on logical thought. What I have are theories. But while I have negative 'symptoms' that I call down time, or depression, I don't believe them as much yet I can't consider they're not real. Life would seem meaningless and incredibly short.
