                                                           I have the same problem - mainly is caused by constant lack of sleep. My advice - try to get better diet, sleep more, and relax more often. Good idea would be to go on a vacation, somewhere near the sea, where you can really relax. Find a serene spot - and really relax - it will give you the necessary energy.
