Is jerking and twitching in the head, arms, legs, and feet associated with anxiety? uncontrollable head movement, head rushes, feeling lightheaded, and none of the head twitching is noticable to any1 but myself.

hi im 22 years old and turning 23 on jan, and my case is having twiching head, legs, feet, arms, almost everywhere in my body. It all started from smoking marijuana 8 years ago and then they all started to develop over the years. First thing happened was we smoked weed on a blunt and this guy kept forcing me to smoke more than enough so i was like smoking too much that i cant handle, and after couple of minutes i started to see blurry and i got so nervous cause i don't know whats happening to me. After that i decided to go home and went to the backyard to figure out what to do and my muscles starts to twitch from legs to head, it was crazy it feels like its spinning all over my legs, and after that my head starts twitching too. Crazy it feels same way as the legs are twitching, so i just pulled my self together and pray to god that it would stop.But i decided to take a shower so the effect would go down and it kinda helped, but since then i've never felt the same me anymore, cause it left me anxiety, or worriness, it feels like a trauma to me, after that incident i always feel weird everytime. It feels like im always in trouble that im gonna feel the same way again over and over so i always feel nervous about it. My chest is pounding hard my body twitches everytime the incident pops in my head, it feels like i cant help it. So for the couple of years i've been having anxiety with all these strange feelings in my body and my head twitching got worse cause it feels like its all over my head now, it twitches or it feel like its about to twitch whenever i feel nervous, and im so scared that it would lead to serious problems.I know i got all these from just smoking marijuana and it cause me a lot out of my anxiety. The most bothering problem that anxiety gives me was having trouble to sleep. I cant sleep at night fast cause of the anxiety makes me tense or nervous so it bothers me and giving me hot flashes too. Over the years new symptoms have developed in my body including the hot flashes and the twitching in my head. At first 4 to 6 years my head doesnt twitch that much or it was just a clicking in my head, i can even hear it when it happens. So in the next 2 to 3 years the twitching began in my head noticebly enough to tell. But only me i meant can notice it cause i feel it in my head when i get nervous or anxiety attacks me. So for the first time i went to a mental clinic to discuss this problem and they prescribed me a antidepressant drugs called zoloft. I was scared to try because i dont wanna have any side effects with it so i decided to get a second opinion first before trying some drugs. The other problem is i dont have medical insurance to cover this so thats why i've only been to clinic once. But since i have a registration with some community hospital i was able to get some help lately, and i have an upcoming appoint. on next wed. and i would tell it all from there. So now im dealing with this anxiety for years and i haven't figured out a solution just yet, and im hoping for good that someday it would be totally gone in my system forever so i would feel the same person again or atleast its not a serious problem to be stressed about.
