Just hold it, i'm glad you invested your money into ethereum and not some other unknown coins. Have faith on it, i'm sure even 700$+ for 1 ethereum is still cheap, i'm pretty sure the price will be much higher than that in a year or so. And please don't go commit suicide! life is too awesome and beautiful for that, don't waste your precious life, please...
EDIT : Just checked into his account and I couldn't believe what I just saw.
I want to know what you guys think

Is $900 realistic? I bought at $900 so I'm hoping I just break even. I don't really think it will hit back to $1000 because of the short pumps and whales taking profit repeating.
I invested $100,000 into ETH when it was at $800. I was wondering if I should sell and re-buy or hold? Will ETH reach $800 again this year?

Dear OP, you are a terrible liar.
I don't know why would he waste his time lying on bitcointalk, maybe he feels alone and like to troll people for fun ?
