A type of high thats indescribable

Has anybody had a type of high where yhu just feel out of the world as if yhur high but yhur alert and yhy just feel something of yhur head its like a lot of worries thats all I can think off ! but this is how the high was for me it was like I couldnt sitt down because just being sitting down would make me go krazy and id have to be walking so I could be calm because I just literally vouldnt be sitting down not doing anything and then id be thinking I would die if I didnt call a doctor or sum its like the worse feeling ever and it lasted for like idks 5 days or maybe 7 before I stopped feeling like that or maybe 10 idks it was really weird i would get that feeling when smoking weed and I dont understand why ??? Because I use to smoke like 3 blunts a day all the tym and id feel fine and idks im gonna try weed again but I stopped smoking because I feel like that like im doing an experiment to see if ill feel someway if I stopped for a while because I cant smoke weed without freaking out and having to freak out just sitting down, having to walk because I just cant stay still and worrying like hell if ill die or not or even hearing voices in my head like myself saying stupid shitt thats soo negative and sometimes just hearing my heart or something !! Has anybody had this ???
