People dont know how to handle that much money... that's why they get all bent out of shape over it.
If you want to stay sane, your best bet is to give as much away to family and friends as you can, use a sane amount to set up a fixed yearly income for yourself, prepare for your kid's college and secure a good retirement...
and then forget that you ever won the lotto. Keep working. Don't become a 'rich person.
