I work for a large law firm, and am burning out fast. Billable hours rule my life, and I have no time to do what I care about (bike, hike, etc). I am seriously considering several positions which will literally be a 50% pay cut (or more). But...I'll do work I believe in (I don't always sleep well right now), I'll have a very short commute (could probably bike) and I'll have time to do what I love. I don't have the answers yet. I had hoped to hang in there until my loans are paid off, but I'm not too far away on that front. And I know I can't do my best work where I am too much longer (there are major changes underway which mean more $$, but less free time and much more stress).

So no, I don't think you're crazy (unless I am too). Just make sure the time is right for you and that if you don't love it, you have options.

Good luck!
