I was contemplating Heideggers idea of Being whose Being is a problem. Self-consciousness to me, whilst directly speaks of consciousness that is aware of its own self as a consciousness, also carries an overtone of anxiety of that state of knowledge. Whereas consciousness seems to have only the connotation of being aware of qualia stimulated externally.
(As an aside, does Heidegger acknowledge the possibility of Being for which Being is not a problem? For if there is no such Being, why bring that distinction, is it only for distinction?)
