Is it normal or healthy to feel/ live this way?

When I get up in the morning, I really do not feel like getting in the shower even though I dislike being dirty. I enjoy being clean and having my make-up and hair done, but I usually do not feel like doing it. I babysit children, and I cannot help but doze off maybe once or twice per 7 hour session. I feel like no matter what I do that it will never be enough: no matter my grades (straight A's), I feel stupid; I buy the clothes I like, but when I wear them I no longer like about half of them. I feel like something is not right in my life, but I do not know how to fix it. It is like I lack motivation for daily function, but I do sometimes have it in quick bursts. Is this normal at all, because I do not recall always feeling this way? I feel like whatever is wrong is negatively progressing.
