i feel strange

i am not very young anymore,but sometimes i still feel like a child.
Like a child i saw lots of wonderful things in life. but sometime, i feel scare.
I don't know how i feel like this, but in last few days, i feel scare and without security. like wandering in a strange land,
i feel like a little child trapped in a strange land, someone or something has control over me.and i feel afraid,
hope it will be over soon.
