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

Is that your life worth? For only 25000 dollars you will commit suicide? Next time be careful don"t invest your money if you are not ready to lose it.Life is more important than money. If you lose money you can earn it again but if you commit suicide you'll lose more than anything else.
