Sleepwalking problem?

Since I was three I've had night terrors where I would scream while I slept and that kind of stuff. Later, when I was about 9, I began to sleepwalk. I would go around my room looking for things, cry because I didn't know where I was, and one time I almost ran out of the house unless my sister wouldn't have caught me. We went to my doctor when I was like 10 and she told me it wears off and that it will be fine. Well, it's continued until it's basically nightly. Last night I hit my walls and windows trying to get out of my room. When I was younger I couldn't remember sleepwalking, but now I can remember the incidents, just not the dreams I had when I was asleep. I'm not sure what I'm thinking when I'm sleepwalking, it's hard to explain. So is my problem going to keep getting worse? Because at the moment it is. Help?
