Can't tell what's real and what's not

Hi.
So I'm seventeen and a Junior in High School. I have always been I guess what you can call a normal kid. I wasn't very popular but nevermind all that.
Ever since the 4th grade, I have been looking at life and everything just seems so far away but then again, everything seems so real. All of my friends tell me the difference between the two is dreaming, in which everything is off and not possible, which seems logical, but the same type of atmosphere switches between dream and reality. Like I said, it's been happening since the fourth grade and it is really starting to upset me. I lose interest in a lot of things because of this feeling. Sometimes, I feel as if I have already died somehow and nothing is real. I remember having dreams as a kid. Dreams where I would wake up, not even remember the dream but notice that everything around me was fake. I knew for a fact I was awake because I would get scared and tell my father during the night. He would always ask about it the next morning. Anyway, I would wake up and everything around me would seem farther than it should be, as in distance. Everything I heard from sounds, to talking to my family members, to just footsteps sounded sped up. Although everything else was fast, I was moving at a regular speed. I don't know what it was but I'd like to know.
Again, it's making me angry and frustrated. I'd like to just move on with my life but it is very hard to through this perspective. Any help is wanted and appreciated.
Thanks

Hey,

it sounds very similar to derealazation/depersonilzation. Iv experiened very crazy feelingz in the past too. like feeling everything seems fake, or unreal. i also felt like i was looking at my view from a distince. It lasted for a good few years, and slowly, but surely it faded away. idk what triggered it, but it coulda been anumber of things.

so have you seen some kind of docter about this?

I've talked to my usual checkup doctor about it. He said the only thing he could explain was the waking up and seeing everything from a distance. He said I must have been still in a state of sleep but I know I was awake. But that's the only person I asked about it who gave me an answer.

Hopefully things gett better for you. i can understand the fustration your going threw
