I Haven't Been Sleeping For Two Years.In Eighth Grade, I

I haven't been sleeping for two years.In eighth grade, I was stressed about something and I got mad at my family....Therefore, I woke up everyday playing on the computer/ doing homework until the next morning without getting sleep. I did this continually for more than eight months. Then, at the end of the summer (August) I couldn't sleep anymore when I wanted to. I couldn't sleep from August until January( zero hours of sleep). I was so sad and depressed; my heart beat was rapid..it beated very fast, and I got headaches, I also had anxious thoughts about pulling out my eyes 24/7...I even skipped eating..I tried to find ways to put myself back to sleep. I read online that you can establish a sleeping schedule and eating healthy and exercise can put u back to sleep...so i did that and it worked, but only temporarily.It only lasted from January thru June...and I couldn't sleep again...I told myself its ok I can go to sleep again, but it turns out I couldn't. So, I couldn't sleep again in the summer of ninth grade...which lasted from June to January....this took place this year of tenth grade...So i struggled to ignore the problem and it kind of went away temporarily somewhere from Jan to the first week of June...and now I can't sleep again... I went to the psychiatrist during the summer of ninth grade and my blood test was normal, so he said it was just a chemical imbalance, but I felt like it was more than that, but I didn't tell him. The antidepressants didn't work...My brain feels like a car when u start it it moves a little bit and a little bit and it just breaks down in the middle of the road... I think from the lack of sleep over the 2 years(zero hours of sleep)...nothing is working anymore even the natural ways...I think there is something wrong with my nervous system....I exercised, establish a sleeping routine, and eat healthy but nothing is working. My head hurts- it feels so tight( like someone is pushing it together with their two hands). I also get headaches from the computer. I tried to relax but something in my body is not going right....From the staying awake a lot ruined my sleep... Now my body and brain is not functioning..I told my family but they said your just like everyone else..but I told them this is different I have 0 hours of sleep for a little over two years. My face is sagging ..my eyebag is bad...I look like a zombie...There is too much pressure on my brain...I feel like some one Just gave me a 0000 gallon of chemicals filled with depression and anxiety Is there anyway I can get this checked out?....do u think I'm going to die? I'm so scared my body and mind is not functioning right....I don't know what else to do...Help me please... I feel like I'm going to become mental from the lack of sleep...Thanks
