Understandably frustrating, especially if you’re new to investing. But it’s expected that the market will have both ups and downs.

The best advice I can give is to choose a good investment allocation and then stick to it. Contribute as much as you can each pay period or month and avoid looking at your balance as much as possible. You should figure out a rebalancing strategy, and you’ll probably need to look at your account to do that. Also, see The Best Order of Operations For Saving For Retirement.

Right now you have unrealized losses, but you haven’t actually lost any money (i.e., you have no “realized losses”) until you withdraw it. As it’s a retirement account and you just started it, I assume you aren’t planning to retire in the next decade, much less the next three years.

Is this your only retirement account? If so, why have you not been continuing to add money to it? If you wait to do that until the market recovers, you’ll lose out on all the gains between now and then.

I know you haven’t said you’re considering selling, but I recommend you check out the “Maintain Discipline” section of the Bogleheads investment philosophy, just in case that’s on your mind. I also recommend that you read up on dollar cost averaging (if you’re investing in a retirement plan every pay period, you’re already doing this).

You pointed out that the entire market has been impacted. I haven’t personally been paying attention in enough detail to confirm that (and my accounts that I just checked have gone up about 10% over the past three years, not down), but if so, that means you could change your asset allocation without selling low and buying high. I’m not saying you should change it, but if you take the time to learn about different investment strategies and decide a different one works for you, it’s nice to not have to sell your current investments while they’re underperforming relative to your new investments. (On the other hand, you can always change the allocation for your future investments without worrying about that.)
