I am 16 years old, I have been feeling strange for about a month and a half now. Since June 28th to be exact. Two days before my birthday. That was the day that I had my first huge anxiety attack. I have always had a mild anxiety disorder, along with tourettes, but it was never, ever this bad. Since the 28th, I have felt different. As if I stepped through some time of door and it was locked behind me. I feel dizzy every single day, I have strange thoughts of death (of myself, others). I am constantly worried that I have some type of disease, or a brain tumor, cancer, or something. My limbs go numb randomly. Light is really hard on my eyes. I have bad headaches, accompanied by pressure in my head (which is the main reason for my thoughts about a brain tumor). I have no desire to go out and have fun, my vision often goes blurry and it always feels like im high or something. it looks like there's a layer of something over everything I look at. My brain always feels foggy, and i'm always scared. I feel so alone because none of my friends actually know what I mean when I say that I feel wierd. I have smoked for 5 years, but I have now cut down to 1 or 2 a day, somedays less because i am convinced that smoking is one of the reasons for this. I drink occassionally, about the same amount as alot of other teenagers. Only once every couple of weekends or so. Never have done any hard drugs in my life. I used to smoke weed a couple years ago, and that's it. But don't anymore because i don't like the effects. I feel like these thoughts that i'm going to die are consuming my life. "it feels like my body is trying to shut itself down and I can't do anything about it". This is no way to live, i just need to know that i'm not alone. Please help me, I just want to feel normal again.
