Yeah, the losses really stink.
I just moved around some of my 401K according to DH's suggestions. Unfortunately, I should have kept my $$ where it was, as I took more losses than I would have.
You have to not look at it, or worry too much. You are in it for the long haul and just think of it as purchasing those shares at a lower cost. You do need to periodically adjust your mix according to your age and retirement strategy, but watching it that closely can just make you frustrated at times.
You are doing the right thing, maximizing your contributions at such a young age. It WILL grow. I know it's frustrating now to see that you could be using that money to free up your budget more, but think about the free money that you are getting with your DH's company match.
When I was your age, and was working, I also wanted to contribute less to my 401K so I could have more take home to use for bills. I did cut down my contributions for awhile. Now that I'm no longer working, I really do regret doing that. I still have a good amount in there, but I could have had alot more. Not only did I miss the growth on my account, I also lost the free money from my employer's match.
Hang in there. The market always has its ups and down. Pretty soon, you'll see your $$ going up.
