Graham Cooke in his website at www.brilliantperspectives.com wrote the following:
If you feel bad enough, would you like others around you who love you and care for you also start to become negative as well?
I, for one, am not going to tell you to snap out of it, as it is not going to be as easy as just saying it to achieve it. If it were that easy, you would have done a long time ago.
However a good starting point is to look for the silver lining in every situation to begin with and change your perspective on things.
Try that and see what happens.
Until the next time!
