Thanks for the query to H.C.M. Forum.
If I were your doctor for this type of symptoms I would come up with these possibilities as.
1 Anxiety or tension ( work related stress) , this may be the cause of your headache , generalized body ache
2 As you are complaining that frequent urination
is there and excessive tiredness, so these symptoms may be due to diabetes . Diagnosis can be confirmed by blood sugar examination as well urine examination.
3 Urinary Tract Infection
i.e. U T I is the most common cause . Diagnosis can be confirmed by urine examination complete so get in it.
In my opinion tension is the most foremost reason so first of all consult a psychiatrist
and get his treatment but after urine examination ( diabetes or UTI).
Good luck. Dr. HET
