What to do? Life is like that

Have you ever have a feeling of hopelessness, helplessness, scared, disappointed, sad, angry and fear of the future all mix up causing you to laugh and cry at the same time?
Life is always full of uncertainty. That's what everyone knows but how many of us can face it with a light heart and full of optimism?
What to do? That's just life. And we still need to continue living no matter what...
I hate waiting... waiting for the boat of life to just follow the current of uncertainty, not knowing what is in front of you, a waterfall or the open sea? Why cant I just row my boat? But life is just like that... without paddles to control your life.
