Is this axiety ? Need advice.

Hey guys i kinda have this weird behiovours ,that i do especially when im alone for example i pull my lips alot ,when im alone I will pace the room imaging some weird sceniros like me debating or some stuff like that and will even talk as if im there (poeple often catch me pacing the room and talking to my self lol) .I do these on a daily basis.Also im kinda fidgety pearson ,and although im somewhat confidentt, in some social situaons i may act very weird i will get nervous af ,talk alot ,blink,move my eyes put hands in weird places or sometimes just freeze my whole body so i can avoid doing weird gesuture (which is also kinda weird).Also if see camera pointed at me i just cannot act natural it looks absoltley ridiclus im like a deer blinded by headlighs.I also can zoom out at times that i shouldnt and when ppl call me out i kinda snap and get jittery again and get embaressed.I also squzee my hands alot epseccially when i do someting satisfiying.That beign said sometimes i act like a normal pearson and can come across as very witty and charming and pretty courages.Another thing is when im alone and even in public i zone out and rember something bad that happend to me and i get obsessvie and do someting weird like chaning my whole face expression and people will ask me is everything ok ? and i dont know what to say or how to explain it. I am also very creative pearson and have pretty strong imagination .Does somebody has something simliar ? Im very curious what is this.
