Hello,
Constant tiredness,fatigue and the other symptoms that you are having can be due to anemia,chronic fatigue syndrome,hypothyroidism, disorders of the hypothalamus,psychiatric disorders like depression and sleep-related breathing disorders.
Pls get your Hb levels and thyroid levels estimated. Also eat a healthy, nutritious diet and take your medicines for depression regularly. If the symptoms persist then pls consult a physician and get the above stated causes ruled out.
I hope that helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.Kind regards.
Have you had a chiropractor look at your back? Sometimes it is related to T6 or T7 (thoracic spine) being out of alignment. All the nerves in your back go to certain organs and produce symptoms when they are pinched.
