Trust me, your not alone. I say, take a month off, refresh your mind, relax, and you will be blazing when you come back. This happened to me years ago when I was learning Java, btw I hate Java. I quit for about a month, but came back with a whole new energy. Web Development is not easy, as a matter of fact, it is quite hard, especially on the mind which gets tired after awhile. If my opinion is right, see ya back here soon!
