You have to stop checking prices every second, otherwise you will go crazy. Read up, buy some coins which appear to be logical buys, and just HOLD. Do nothing, don't try to day trade, don't try to outsmart the market. Never panic buy and never panic sell. Up until now, every major coin has bounced back from drops, so unless you have invested in absolutely useless coins (which, based on your portfolio, you haven't), just be patient and don't panic, even if your numbers are red right now.
