Thank you for your question on the troublesome problem of urinary frequency. You don't mention that you suffer from any other related symptoms.
But frequency can often be associated with 'urgency' (a sudden need to pass urine) and difficulty in controlling the bladder to the degree that one may be incontinent.
If you are troubled by these symptoms then I would recommend that you seek help from your GP or practice nurse.
The bladder is emptied via the urethra
by contraction of the normally relaxed 'detrusor' muscle that constitutes the wall of the bladder.
Lower urinary tract symptoms
such as problems with frequency, urgency and getting up at night to pass urine are commonly related to an irritative bladder muscle (also known as detrusor instability).
An unstable detrusor also contracts in between voidings. This causes high pressures in the bladder that may be felt as urgency and give rise to urine leakage.
Rarely a deficiency of the hormone which controls the body's water balance can result in urinary frequency and thirst.
This is unlikely in your case because of the length of time you've had your symptoms but again it is something your doctor can investigate.
