Ever since I was very little I have had trouble falling asleep and staying asleep. I've never slept a whole night, and I still wake up several times during the night. My doctor gave me some mild pills that should help me fall asleep, but it didn't work. My parents keep saying that it's normal to not sleep much but I don't think so. It is like that every night, even on holidays and weekends. I'm born with a heart defect so I think that may cause it. I also often wake up very early in the morning which is annoying. I'm getting tired of it because my parents don't understand my sleep issues. They think that I'm very childish, especially if we have to wake up early. I really need some advice because it destroys my life and I can't concentrate during the day. I can't go to the doctor by myself. What should I do!?

Sorry for grammar mistakes.
