s brat!  It's not only you who feels depressed... everyone feels that way when things don't happen the way we wanted it to happen. And; we feel happiness when things happen the way we wanted to happen.   This is the nature of our mind.  Life is full of ups and downs..  as a result; we feel joy and sadness in life which I think we should take it easy. We should not forget that nothing last forever... even the hardest times we experience..... like a beautiful morning begins after every  long dark night.  It only takes a little patient. Exercising, thinking positive and a little bit of spirituality also may help ease depression.  Go to :   www.dhamma.org  It is just a suggestion, please don't take it otherwise.
