I invested half of my saving ($25,000) into ETH when it was $725. ETH has now plunged to $459. I am very worried I will keep losing money and I fear for the worst. I want to go kill myself 
Money can be lose and there are hundred ways to earn and look for it again, but life, is hard to have when you lose it, you can sell your ETH when you need money but if you can sustain your daily life with your job or business then, hold unto them,lets wait for the market to recover.
