Hi, About a year now I have a few symptoms that have been really slowing me down, at work and otherwise. some of the symptoms are; - Feeling fatigue and tired all the time. Even after a 6-7 hour sleep. However, owing to the nature of my work, I do work really long hours, sometimes 12-15 hours a day. I try to compensate my lack of sleep on the weekends. - shortness of breath. I find myself sort of breath and breathing fast. - tired eyes. I can feel my eye balls tired and heavy and also a throbbing in the eyeball. - periodic headaches that sometime get severe like a migraine. - fast heartbeat. Do I need to get this checked? I am 42yrs old. Thanks
