Sacrifice My Life For Others

I know many people stand behind me to support me all the time,they love me very much in silence .I need to take some actions back to grate them ,but I think I am not brave enough to sacrifice myself for others alive.If this situation really happened in my life,I would try mt best to save them .I would find some help from others if I cannot afford to make them safe .But at that moment,I couldn't choose to take their place instead .It's silly and emotional decision.Even friends and family members are important for me,but to be honest,I would be indecisive and timid to stand out to volunteer for them.Some people think I may be coward and unfeeling ,I don't really care about my friends.Actually I did,although I can't be a hero and be awed by others for my behaviors .In fact,we always say we love someone even we die for them,but there are few people really taking actions.When I face the big disaster ,I would make myself safe and take care of myself first.Then help people who are important for me.That's all I would like to do,it doesn't mean I didn't love them.I really love them so hard,and I would like to volunteer for them,but I also have my life to control .This is my choice.
