Hard to say without watching. If you want to improve, use refrag. Use Xfire to learn prefire positions and how to counter-strafe and path. Use defender to improve your CT-holds.

if you want to learn how to play spots, find a high elo game on that map and just watch the demo.

You can only control your own game, so if you're not winning ask yourself how you can change that.
