Well, don't want to loose a big chunk....going to need it in a couple years.
with nearly everything down, you will likely lose money now if you sell. best is to just hold and wait for the market to recover.
Always good to know your cost basis and when you purchased so you can adjust what you paid to today's dollars to determine the paper loss or gain more accurately. Especially before you sell anything.
if you're planning to retire soon, look into "sequence of returns risk" to be sure you understand its' impact. It's one reason why I track my change in market value on many time scales (monthly, quarterly, YoY, yearly, over several years etc.) For example if your change in market value annual average for the last 10 years is $X and %Y, it will tell you how much (on average) you make or grow (or lose) in your account(s) per year.
If you withdraw that full change in market average annual value out each year, it will impact future growth/income because you're reducing reinvestment. The ratio of what you need (for living expenses in retirement, i.e., your withdrawal) vs what you make (in change in market value), is up to you.
All IMO, of course. I'm not a financial advisor; but I learned early on that no one cares more about my wealth than I do, so I learned how to manage it for myself. Doing so enabled me to become an accredited investor in my 30s; but I made plenty of costly errors along the way too.
Good luck to all!
edit: and of course, the tax implications of anything you do!
