Help me...

When everybody born in this world, there's already a barrier that protect them from everything. But most of the times, they all will open the barriers and let themselves being notice or learn many new things. As for me, i would prefer to stay in the barrier and lock myself up. By doing so, i can keep believing that i would not get hurt and people won't try to look down on me...many people advise me to unlock the barriers because it is not good for me but i don't know when will i unlock it because i'm scare to get hurt...
