Life - Complicated?

Sometimes I feel that life's too complicated for me to handle and understand. One problem solved another comes, and never ends till this so called life is over. We live thinking about tomorrow never knowing what tomorrow will bring. Sometimes I think life is a big risk, if I don't take a step forward I will never reach my goal and to reach that goal I need to take a lot of risks. But pretty scared to make mistakes. They say we learn from our mistakes but if I am scared to make mistakes I don't learn anything. When I do make mistakes, I drags me down. What complications?!!!!
Don't you ever feel that life could just go on as you wish- not creating problems and troubles for other which again is not possible. Complicated?
You fall in and out of love - wishing that the person you are seeing right now is gonna be "the one" but then they leave us behind again. Again making life more complicated?
There are lots and lots of complications in life - the only one who can handle it will be the one who are satisfied in having GOD and I am not that kind of person though I do believe in HIM.
