of course this hurts and I realize that investing in cryptocurrencies is terrible,
my advice if you have $30000 I hope you don't fully invest in cryptocurrencies, better buy gold or land.
My condolences to you on your loss, but I have sincere advice for you. If you are not savvy enough to invest and you cannot accept the risk then you leave the market to avoid losing more. Cryptocurrency is a roller coaster so it won't be suitable for risk averse like you, if you want high returns, you have to accept higher risks. Come back when you're more ready.
