If I started a business and expectedly lost more money buying stuff/expenses than I would earn by the end of Dec., what would happen at tax time?

I heard people were jumping off buildings because they lost their money during the depression. The money they kept in the bank. Even bank money wasn't safe then?

Do i need to pay taxes? A few stocks I made money on and a few I lost money on. Overall I am down a few hundred dollars. I really dont know how this works. When do I pay these taxes. Also where are the forms I need. Thank you. I am a college student , and I am still a dependent. Also, I have only made a few hundred dollars from a job on campus if that matters. I double checked and my first trade was in January. Does that mean I don't have to worry about this till I get the forms next year? Thank you. THANK YOU EVERYONE FOR THE HELP!!!!!!!!!!!!!!!!!!

Yes, if anyone who reads this question helps me find an excellent attorney to find a legal way to recover the money I lost at some online casinos I would handsomely reward that person. This would be a tough fight since online casinos must have excellent attorneys and they have audit firm approval. I have a sure way to prove how the games are biased. No discouraging, negative answers that do no good whatsoever, please.
