If this makes you so nervous on a single day, you might want to think about different ways to invest your money. Nervousness + OTC stocks = lose your money most the time.
Not attacking you at all, just saying it's extremely important to be able to stay even minded on the ups and downs. It looks like you invested maybe $15k back in early April so you should have a nice position. I learned some hard lessons giving in to nerves over the years as well as not selling when I should have.
If you are not sinking more money into it by buying dips, My advice would be not look at the stock at all and come back in 10 weeks to check in. You don't want to stress this churn and you don't want to sell anytime soon anyway.
