Wow, I'm sure sorry for the loss. I would walk away from the hobby without looking back! You've got cajones to stick around, I've got 4 kiddos too and know how attached they become to our hobbies. Good luck with the reboot.
You may want to have pidge or craigar look at the way stand structure/support is designed. Another opinion from guys who do DIY builds may not hurt. I believe a glass aquarium needs equal contact/support along all outside seams (versus acrylic requiring along the entire bottom panel), and it looked like in some of the pictures on the other thread that just the corners are supported. It seems that would concentrate >massive< stress on the long middle seams, especially on a tall high gallon tank. I'm not an engineer so maybe you should ignore me.
