I'm 30/f. I have been experiencing fatigue for the last 6 months and it is getting a lot worse. I wake up tired and get more tired throughout the day. By 2pm or so, I'm so exhausted I can't think straight. It is now impacting my job and everyday activities.
I get 8-10 hours of sleep every night. I don't yawn excessively or have any muscle fatigue, I just want to close my eyes and go to sleep. This started 6 months into a new diet for weight loss (healthy, balanced, 1300-1500 calories). I was losing weight consistently for the 6 months prior but the weight loss stopped once the fatigue started. I did go off of the diet recently and started eating more just to rule it out as the culprit.
I have had a lot of bloodwork. Thyroid, vitamin D, B12, magnesium, CBC, and more. I was tested for sleep apnea and it was negative. I'm not depressed. According to everything I am perfectly healthy. It may be worth noting that I have been on a high dose of vitamin D for a long time because I am chronically low and live in a cold/dreary climate. But my numbers were great in my latest bloodwork.
I have had a lot of negative experience in the past with doctors not putting in enough effort once they rule out the obvious problems, so I am looking for things I can ask about at my next appointment. Any help or insight into similar experiences is greatly appreciated.
