my fear

Honestly i have many fears, but the thing that scares me the most is darkness. this is my major fear. when i was a child i always want to sleep with my parents until i had a sister to sleep together; only because night is a horrible moment for me. the moment i figure out darkness outside, i have all sort of horrilbe pictures in my mind. a lot of time i have nightmare during the sleep. That make me feel bad. I cannot afford standing in darkness alone even for 5 minutes. Back in my country i used to spend 1 or 2 nights alone when my parents travelled; these were the most horriblle moments of my life. I turn on all the lights of my house to be able to sleep. Peole think that the reason is that i wacth horror movies. Now to overcome that fear , first i decided to stop watching any movie showing death, violence , stuffs like that. I also used to sleep with light on in my room. I try sometimes to face a night without light but in the middle of the night i fail from doing it. i don't know how to do get rid of that fear.
