I think all the hints are already stated in the OP's post. What we should do more to it, my own experience and advice is to learn from this mistakes and try to learn again trading has no end of learning. Losses can't be avoided however this things can be done with less risk and you know what to do next time before you gonna lose that amount.
In my opinion if you lose $2000 in trading just let it all passed because you couldn't make anything to return what you've lose but you can make up with your mistakes. Learned from this mistake of yours and move forward keep on trading if you'd still have the courage to keep on doing it because best lesson comes from the biggest mistakes.
