k so its been a a couple weeks over a year now and this is what has been happening i used to smoke marijuana i was 14 by the way now im 15 and i smoked it for a bit and it was fine nothing major just once or twice at a party or something and then one time i got a huge panic feel my palms got sweaty and my feet giot cold and numb and my toung went numb so i didnt smoke weed after that, so a couple weeks later i thought it would be fine to have a couple of puffs with my dad cuz he also smokes and again i got the same the next day i woke up and was totally detatched i felt like i was in a haze and i couldnt think everything was really bright and looked slightly unreal in the next couple of days it became unbearable so i told my parents about it they said i should go see my doctor so i did and my doctor told me to get my blood taken and i did about 4-5 days later the tests came back and they said that i had a very very low iron countso my doctor said to buy iron pills he said take 3 a day for about three months so i did what he said i took 3 a day but i only did it for about a month and a half because i saw little improvement.and now ive kinda gotten over the sensation of unrealism but i still feel like im boxed and not flly aware of my souroundings and i cant concentrate on anything barely. i have the wierdiest thoughts and i cant controll them they are very scary thoughts i just feel like im not all there also i have violent mood swings at one point ill be fine and happy and think the best of situations and then i will be utterly depressed and think the worse of every situation i feel like im going crazy also when its dark i see flashes of light lalmost like fire flys does that have anything to do with anything ? please i need some help i just wanna be normal again ?? by the waay i haven't smoked pot for a year now
