I'm constantly feeling "out of it."

[CaitlinKMorgan]

I'm 17 years old, and for the past couple of months, I have felt very uncomfortable. I'm ALWAYS tired, which I know is something common for teenagers, but this isn't normal. It's to the point that I don't want to hang out with my friends. I would much rather sleep.
Along with the fatigue, I've felt dizzy/foggy headed. I can't concentrate on school work, so my grades have been slipping. At work, I'm forced to sit down every once and awhile or I'll feel faint. I eat well and I drink a lot of water.
I've been known to have anxiety and panic attacks, but I still feel this way even when I'm not anxious or panicked.
I also pretty much have a constant headache, sometimes behind my eyes and sometimes all over my head. My shoulders and neck are always sore as well.
I've visited the chiropractor and it didn't help.
I've visited the doctor and been checked for mono, anemia, and dibetes, but I was free from all of them.  
I am currently on 20 mg of Celexa a day.

I'm tired of feeling like this, and I really want to know what is wrong with me! Any ideas?

Hi
Welcome to the MedHelp forum!
Extreme fatigue could be due to hormonal imbalance of PCOD, anemia, diabetes, hypothyroidism, or due to kidney or liver problems. Another possibility is sleep disturbances (like sleep apnea, imbalance of rapid eye and non rapid eye movement sleep etc.). You may sleep your customary 7-8 hours and yet feel fatigued. You need sleep studies to rule this out. Other possibilities are chronic fatigue syndrome, depression, low Vit b12, low iron, low calcium, sodium and potassium. Hyperthyroidism too causes increased sweating and tiredness. Postviral fatigue syndrome is another possibility. Persisting EBV infection or mono can also be the cause. A comprehensive investigation is required keeping all the points in mind. Do discuss this with your doctor and get yourself examined. Take care!

im sorry you feel this way hun..i feel that way ALOT my self as a suffer from a couple diseases. i know u probably dont want to hear this,but to me it sounds like stress related. try taking a womans multi vitamin i take ALIVE vitamins or prenatal. they give me energy but not like a energy drink..sounds like u r healthy and doing everything right,but stress can cause major problems..or it could be something else,if u still feel bad just try to go back to the doc,or try to not think about it too much if u have ruled everything else out, cause u will drive urself crazy. i know cause i do that myself ;) good luck!
