I wonder if you also said that to your teacher in school/college when you're not earning a cent with what they are teaching. "I spent $2000 in this college education and haven't made money!". The important thing is you learned. You can always get your money back in the long run. Don't give up! I'm also losing money for a few months now. Throwing money away just to learn PPC. I just wish there's a better way.
Learn from your mistakes. Find someone to collaborate with you. Don't be a lone ranger. Don't give up. Keep trying.
Please mate do not worry! I did the same thing as you, but I wasted $500, now I am living off a few dollars and need to work hard for money! That is all changing though, from just a few $$$, I have started a forum and marketed it for free. Now I am getting loads of unique views and I can get all the money back that I wasted. Just try selling anything you brought before, in the BST Section here and maybe use them for some websites, that you can sell and make money back from!
waste some more. probably at some point, one of your projects will work, and you'll end up being one of these filthy rich web entrepreneurs who pays programmers $5 / hour
have you considered donating your $? surely there's a bunch of people around here who would really appreciate it.
I know exactly what you mean. My suggestion is to sit back, relax, breathe deeply, think of that 2000 as a bit of a loss that may be gained back, and why not try working with what you have already? I'm sure they'll be able to work - just spend a bit of time and be patient and try not to push yourself and your expectations too hard.
