Uplifting?

I am loving my company.  My sister always makes me feel good and it is great to have company.  It was brought to my attention that my blog is a bit of a downer.  I have to admit it has been a catharsis for me but maybe I am bringing everyone else down.  That is not me.  I manage to look at the bright side.  So, how do I cheer myself up and how do others do the same.  Please reply if you have any good ideas.
