Hi Sophia

long time no hear
Even the best of us don't feel secure all the time .There are many different things you can do to chase those insecurities away. Just start with the small things and work up to the big ones that wont seem so big once you get there
If life was just so filled with the knowledge that whatever we do or want or feel would just appear and not have to worry about anything. Life would suck after awhile.
It is the little insecurities about life and all struggles we go through that makes us stronger for the next round.
Share your fears with someone you trust and little by little life will smile back at you I have found that to be case many times .You are a strong person don't forget that is always around you
