where does your courage come from?

I am afraid being alone in a long jounery to some place which i have never been to before. I feel uneasy and lack of safety cos of so many new faces and new environment which let me feel alien and anxious. But if i have a strong motivation to do someting, I will be brave and tring to calm myself down, talking to myself,'nothing to be afraid of,and you'll have a nice journey.'Maybe sometime we should give ourself some positive philosophical hint to let us put off that negative thought.

I am afraid of many things but usually I am able to keep going for my children . I don't want them to grow up with my fears and for their sake try to appear like everything is normal . If I can get someone else to do whatever it is that I am nervous of then I will get them to do it for me but if no one is around to help then I will get my courage from my children just because I will do anything to protect them from not having the same fears as I have as I understand that we all have fears for a reason and it is something we have to overcome ourselves in order to get rid of our fears .
