A lot of people fear uncertainties of life. How should they deal with that?
Turn back and look at your own life. How many times have you felt like that? How much time have have you spent worrying? Even though you worried so much, things still happened in the right manner, didn't it. There was no need to worry! So looking back at your own experience, you should see that it is futile to worry. Second is, you should have confidence in your own ability, and in your own fortune. You should know that only the best thing will happen to you. Have that confidence. If these two things don't work there is a third option. Invoke valour in you, "Come what may I will face it, I will handle it. I have the power to handle it". Okay, even if this doesn't work, know that there is a higher power that loves you dearly, and it will never let you down. This faith will pull you through any tough period.
