Paranoia

I'm only 15 and I think I may have a sleep disorder. Its 5:16 in the morning and iv only had 3 hours of sleep in the past 72 hours. Its always like this. I hear noises all night no matter where I am. Houses I use to be able to sleep in no problem, I now hear noises all night and cant sleep. My entire life Iv had a phobia of someone hurting me threw the night and its only worstened with time. I have no idea of what to do. If anyone else has this problem can you please help me?!?
