Wayne, good news that you're out of the hospital. I really hope you and the docs can pinpoint what happened to you. Not knowing stuff like that is rough, and it's kind of draining while you're doing all the tests, etc. to try and figure it out. Good luck man, and vent on RC all you want!
Speaking for myself, there is definitely a point of too much planning. I've sketched out my tank, bought a hulking skimmer and 2 100G water storage containers, only to realize after living in our new 120 year-old house, that there is NO WAY i'm fitting a 300+ tank w/ a fish room into this house until I win the lottery and add a new wing to this house, including digging out more basement space! And then I started figuring out how long it would take me to dig out the basement myself! LOL. So as long as your build is taking, some of us have it worse, man.
Take care. The state of Florida doesn't want anybody seizing up on a pink bicycle anyway.
