There is only one person who can change the way you feel: you.

Doubt, while sometimes being overwhelming, seperates the intelligent man from the non-thinking one. Those who don't doubt things don't learn. Doubting is a form of questioning imo. Like anything else it can be taken to the extreme but I certainly appreciate my ability to doubt things....it means I am doing my own thinking.

If life seems that black to you you should look into getting some help. Just remember that NOTHING will change for you until you start changing it. And what you see everyone else enjoying about life can indeed be yours as well. It is all in your hands.

Good luck.
