Why do things happen?

Hello to you all'

I just wanted to share with you a strange experience I went through...at least it is strange to me!
It was around two or three months ago when I got robbed by three guys right in front of my house. Ever since this happened I started thinking the worst about every person I saw on the street. I always think the person is going to do something to me, I have even scared my parents with my ideas that everyone is a thief. So, I was walking toward the closest store to my house and there was no one near, no one outside playing football or simply just walking around. That kind of scared me, out of nowhere I saw a man on a bike riding towards were I was and the first thing that came to my mind was "This can't be happening, I’m going to get robbed AGAIN". I was scared to death thinking that this man was going to rob me or even do something to me. I started walking really fast to see if I would get to the store fast and when the man passed right by me, he said "Good afternoon and God bless you"!
I replied back and just kept on walking. All I wanted to do was laugh at myself because everything that had me so scared did not happen, the man was actually nice. I walked home confident that nothing was going to happen, I ran into two men with a woman and I even said hi smiling to them and they really happy said hi back. The best part was that in that moment I did not have even one bad idea about these people, I just felt to great with myself and extremely thankful with God.
After this happened I learned not to judge every person I saw, because I do not even know who they are, not to think they are all bad because the truth is that not everyone is a bad person.
I promised myself that every time I get afraid I am just going to pray or ask God to help me take away the bad feelings and I know He will because he is a Father of good.

This really made me think, if I always trust in God nothing is going to happen to me because He is who takes care of me, loves me, protects me, and makes all bad get away from me, but if I do not trust in God will He always do all these things for me? I think He would but it would make Him extremely happy that I always trusted in Him and always felt safe wherever I go and with whoever is around.

This experience really help me and made me realize that I had not been trusting in God, and that maybe this was just a way to wake me up and learn that I can not do anything without Him in my life. I am definitely changing these parts of me and I know that God is feeling proud of me.
