Not insane, I'm in an identical situation.

Right now you're getting screwed by UI. As mentioned by someone, you can switch suppliers and get a cheaper rate (I switched to $0.15 from Constellation when UI announced they were increasing to $0.22).

Before that, it seems your apartment has always been very inefficient. I have a very similar place (2B2B, ~1100sqft) and my baseline daily consumption is around 8-9 kWh which I blame on very old appliances. That, plus poor insulation and crappy A/C and I was paying $600 during summer and $200 even in this very mild winter.
