Take a 1 week break, don't think about music, don't watch it... chill... hang w/your girlfriend, have fun for a bit, then come back. You'll be amazed.
Alot of what's happening is your own mind is messing with your decision making. You are probably wanting to do better, striving for something different, and it's not whetting your palate. Same as writer's block for authors... just relax and come back to it in a week.
Don't pressure yourself too much. Remember, for success in this industry, talent only takes you so far... after that, it's who you know.
