Mood issues from cholesterol meds?

I think I’m having some sort of mood issues from my meds. Is it from low cholesterol? I take statins, zetia and repatha, also eating a low fat diet. I have intense depression, fatigue, random crying, daily SI, and feel like I’m disconnected from everything. My vitamin levels, thyroid, and all that was normal last time I checked. I don’t see my doctor until January. Anyone else experience this?
