As someone in a similar situation, just throw it all in VTSAX vanguard or FZROX fidelity and let it sit for the next 30-40years. Dollar cost average over the next year maybe if that makes things less nerve wracking.

Obviously we are in a really crazy market right now, and while that might be disconcerting it is the case that s&p 500 has existed through 2 world wars and a Great Depression and still delivered returns.
