It is really unfortunate but world was never fair. I lost all my money too and I don't think that people will help you or me. They rather rob us from more, suck already poor people more and more. Nobody cares about others. That is the law of this world - if you are unfortunate, you gonna die alone.
It's all a learning opportunity. Like for example, the OP said he wanted to sell high and buy low. When people do that, for you to gain, others have to lose. So maybe this experience will cause him to think more of those people. It's a horrible game.
