Can mood stabilizers cause you to lack emotions, decrease sex drive, and kill nostalgia?

I've noticed a decrease in my sexual desire and the pleasure I derive from great music. I used to merely look at a girl and get a massive erection. Now, it takes a bit longer. Moreover, fantasizing about women does not turn me on like it used to. I just feel dumb in that department, despite being able to get a throbbing erection when watching porn. I have a short history of depression and I am Bipolar II. I am almost tempted to go on anti-depressants and coping skills alone, because mood stabilizers such as lithium and abilify are making me feel like a zombie subhuman. On the other hand, my lab results said that I had low levels of lithium. What does this mean? Moreover, I can no longer get nostalgic about my past. It used to come so natural, but that spark seems to be dormant. It makes me feel disconnected from my blissful and passionate old self, to the point where it's almost as if we are on two separate plains of existence. I hold the pills directly responsible for this. Overall, I feel less perceptive and imaginative.
