Last night i felt really weird, then my head jerked up really quickly and my left leg started shaking. it lasted a few seconds and i didn't lose consciousness. then later on i had mild chest pains (which i have a bit now) and my left arm started aching the aching came first then the chest pains, then i fell asleep as was fine in the morning. What happened last night (the shaking) has happened about 5-6 times before. i also cant control what i think or say sometimes, like the other night i told someone i was going to go on a gun rampage in town then kill myself, which i would never do. And sometimes out of anger i say some really really nasty things to people usually along the lines of "im going to track you down, slash your throat open, drink ur blood and hold your eye lids open so the last thing u will see will be my eyes". im shocked by some of the things i say. my hands and arms sometimes feel still, my hands feel stiff right now. my right hand feels colder than my left hand. i also have random spurts of depression and anxiety what come out of no where. i used to smoke cannabis alot and since i started it 3 years ago i've always seen this semi-invisible dots everywhere i look, sometimes they form little images, i see them everywhere. i also have noticed my memory becoming worse, i sometimes forget what i've just done or said. and i cant hold my left hand still. and right now i have mild chest pains. and my feet and hands feel tingly sometimes. and occassionally i see a flash of white light like off of a camera but it lasts about a split second. Any advice would be appreciated i dont want to go to the doctors because i often go to him with things that turn out to be nothing.
