I had many of those same symptoms for several weeks after I quit. Obviously if you are concerned see a doctor, but honestly it takes our bodies more than just a few weeks to completely recover from long-term binge drinking. Think of how long your body takes to adjust from just having a bad cold or the flu for some perspective on things.
I can also say that "waiting for a miracle to happen" is most likely setting yourself up for failure. Life has it's ups and downs, regardless of whether we are sober or not. It's up to us to learn to deal with it in a positive way - what have you been doing to further your sobriety these few weeks? There are a lot of things that can help - meditation, exercise, conversation with others in the same situation, counseling, therapy, reading self-help literature, the list goes on and on. Reading and writing here on SR itself can be very therapeutic itself...have you considered joining one of the monthly class threads or the daily threads?
It WILL get better...but you have to be patient and do the necessary work too.
