you cant be on top of the world all the time, try takin some "me" time out just for u. we all get down days, pressure of life, kids, work, money etc. we are living in very fraught times. sometimes just to get away from it all even lockin yrself in the bathroom and having a good old cry can help. take it from someone whose been there, done it and got the tee shirt. A nice long walk sometimes helps too, especially if u can walk near water very theraputic. hope this helps x
