It's sound to me like you need to look at the world with a new pair of glasses. I was in the same frame of mind at one time - and it was a gift because I learned to see all that is wonderful in life in spite of the negativity that can cloud it.
You don't need to set and acheive goals or do any of the worldly things that so many get caught up in trying to find happiness and meaning. Everything we need is already inside of us and it just needs to be accepted and let out.
We are spiritual beings having a human experience - please don't let the human experience destroy your spirit.
