A few days ago I saw some scary videos on Youtube. Since then, I am feeling a bit uneasy. At day time I am alright. But at night I feel very scared. I am feeling very disturbed right now. This is happening every day with me. As soon as the sun sets, fear starts occupying my mind, esp. When I am alone. I am scared that I will lose my mental balance someday if this continues to happen. Please help me. Suggest me a way to overcome this fear of mine. I have also developed a fear of darkness now. I need help as soon as possible. I want to live a normal life again as I used to do a few days back.
