Ok, you feel you got hooked. You can't do anything about this time, except learn for next time.
I know it sux. I'm sorry you feel used. Somethimes it seems like no matter which path we take, the results aren't what we'd hoped for. So, keep to the high road and if you don't have one keep a journal of the "positives". It's way to easy to focus on the negative stuff and then we miss what's working.
