This is normal, OP. Growing as a disciple of Christ is realizing that you constantly fight against Him and need to have the humility to just stop relying on what you think you have (but that in reality is God's) and to rely on Christ alone.
I wouldn't receive the Eucharist with a wavering faith if I were you, though. If you can't seriously say the creed and mean it, you probably shouldn't commune.
My faith can probably be better described as bipolar - I think about Christ daily, read the Bible almost daily, buy food for people in the street when I can, and go to Divine Liturgy whenever I can, yet I indulge daily in sex, drugs, and/or alcohol, and feel a lot of pride for myself and hate for others. It doesn't help that I am also literally bipolar, I guess. I'm obviously not in a comfortable situation though.
