Join the club. I'm rated and I still don't consider IFR training to be
"fun." The first 20 or so hours are a bear as you are struggling to
integrate so many pieces together and are spending most of your time
behind the airplane. Stick with it and it will eventually come around.
The key is frequency- if you're flying less than twice a week you're
making it harder for yourself.

Can anyone remind me why I'm inflicting this on myself?

The best reason I know is because you want to use your airplane for
transportation with some reliability. Of course, not every
pilot/airplane is up to every trip, but having the rating is pretty
much a prerequisite for this in much of the US.
