I'm always tired and my body aches. Why?

I usually get about nine hours of sleep and I'm ALWAYS tired. I do not even know how I'm able to survive through each day. As I type this message on Yahoo! Answers, I'm yawning and am feeling very tired (or fatigued). I have not felt good for many years and I'm only 17. I'm 5' 7" and I weigh 108lbs. I have been to the doctor, but they continue to not listen…

I do not have a good diet… I'm the worst eater. I only eat a few foods, most of which are served once a week in my household. I would say the only healthy meal I eat each week is Italian Chicken, Broccoli, and Mac n' Cheese. I usually snack and eat pizza. If I could eat chicken everyday, I would. I'm probably one of the world's worst eaters, as I'm actually "afraid" of some foods. If you get near me with an egg, I will literally freak out. It is a problem that the doctors say I will grow out of, but I doubt I will. I have never been a good eater and I never will be. I can't stand the texture, smell, etc.of most foods. I guess that explains my weight problem… Though I would expect to weigh more, considering I eat so much junk food and I'm not active at all.

I'm also always in so much pain… On some days, I can barely walk, as I have pain that originates in my knees which goes up and down my legs. It is very painful and sometimes I feel like I'm going to fall… I do have balancing problems and I trip far too often. I have been to the doctor for my knees too, which the doctor simply ignored… He did an x-ray. I think I need an MRI or CT Scan.

I have very bad OCD -- I can't even begin to tell you how badly this impacts my life and the daily struggles I go through to cope with my obsessions. It takes me nearly 30 minutes to actually begin to fall asleep -- I constantly check my phone to make sure my alarm clock is set. I'm very protective of my belongings, making sure they are aligned evenly with the table and away from anything that could harm them (belongings include my MacBook, iPhone, Etc.).

I also suffer from Aspergers Syndrome. I believe that I'm Bipolar, as I have mood swings every few months. I have never mentioned this to my psychiatrist. I basically go through periods of feeling great to periods of feeling depressed -- which I believe stem from my obsessions and a lack of social life.

I do not think I will ever be happy and I definitely can't keep living like this… Between constant worry, obsessive thoughts, and chronic tiredness, I do not think I will ever be able to survive working in a professional environment, much less keep a steady job.

and I can't seem to make my family understand…

I had to go back and edit this before publishing the question… Because I had two sentences/paragraphs that had a single word standing on its own line… That drives me crazy! I also sometimes randomly capitalize words to make a sentence look right.

Have your Thyroid checked.

I wouldn't go to a doctor. Doctors want your money. That's what they need; sick people. Doctors will give you temporary relief just to make you more sick later, so you come back and spend more money. They will tell you to eat red meat for iron and drink milk for calcium. Both will make you very tired and make your body ache. Try eating vegan for like… A week. You will see how your body will function more properly and you'll be way less tired. Try it.It'll work.

Also, I don't think you have very bad OCD. Everyone can be a bit compulsive sometimes. You have OCD alright, but based on what other people with that illness do, I think you will grow out of it.

As for the mood swings, it might be that you don't have enough vitamin D. Ever heard of that depression that only lasts throughout winter? That is because in winter, people don't go outside that much (sun=vitamin D) and there's less sunlight. Doctors won't tell you this because, again, they want your money.

Whatever you do: Don't eat meat for a week! Just one week. If you can, eliminate dairy products as well.
