Think about why you cant please your manager and give specifics. Be able to analyze a problem subjectively is 50% of coming up a solution. The other half is actively dealing with the problem at hand.
Feeling out of control and tired isn't going to take you anywhere. It's ok to give up when you conclude you've done everything you can and be prepared to live with the decision. You can get mad or angry but don't ever lose control. Sometimes going a different direction will turn out to be a blessing.
