If you're only down 7.3% YTD, that's not bad. As of yesterday morning, I think I was down around 17-18%. I'm a bit lucky, in that I'm able to work from home, and haven't had my income dry up.
On one hand, it does feel nice, to be able to keep investing in my 401k, while prices are low. But in the overall scheme of things, it probably doesn't make much difference for me. I had hit roughly $2.048M on February 19. The ~$883 every two weeks I'm adding to my 401k, even at these depressed prices, doesn't hold much sway at all.
The bigger advantage, however, is having steady income still coming in, instead of starting to tap my investments to cover expenses.
Anyway, it sounds to me like you're doing fine so far. These are uncertain times though, so it's reasonable to be nervous.
