Without a doubt this can be incredibly frustrating, however as long as you invested in good coins then you have nothing to be worried about and you just have to wait until the next bull market comes, however if you invested in coins which are highly speculative then you may have reasons to get worried about, as a great deal of those coins will never really recover and even if you could be able to hold you coins until a new bull market appears there is no guarantee the coins you are holding will recover.
