Is there anyone else in the same boat? I have had feelings of tiredness for the last few months. It would be wrong to say that I am tired ALL the time, but my energy levels are certainly much lower than before. In combination with the tiredness, I also have headaches (probably because of the tiredness), my eyes have a weird pressure and I feel slow and just not myself. What are the side effects of this and what do you think is wrong with me?
That sounds awful! I am not sure what is wrong with you, but it sounds like you are in serious need of medical attention. These kinds of symptoms can be caused by almost anything, ranging from simple medical conditions that are easily cured, to complex diseases. We can't diagnose you online, so you need to see a proper doctor.
Can I just ask you what your diet is like? I know that I don't eat as well as I should - and that is an understatement - when I am working over hours and am stressed at work. In weeks when I do a lot of work, I tend to just grab a burger or something similar. If that goes on for too long, I start feeling the way you do now. Could you be feeling tired and lethargic for similar reasons?
