This sounds like a very difficult thing to cope with — and quite unnerving — not to be able to identify yourself. I appreciate the courage it takes to explore the condition, however it would not be possible for me to make a diagnosis of depersonalization, derealization or prosopagnosia (pro-so-pag-NO-see-uh), a condition where one someone cannot recognize their own face. While there can be a variety of possibilities the best thing is to begin with a complete physical. Let the physician know all the ways this is happening, and he or she can help get a proper diagnosis as there are some physical conditions that may be causing this that you would want to rule out. Also, a neurologist or psychiatrist could help determine if it is physically- or psychologically-based. An accurate diagnosis is the first step in finding a way to manage and treat these symptoms.
