There are a few conditions that can cause a long-term itchy rash in the vagina (otherwise known as pruritus vulva). Fungal infections, eczema and psoriasis are all examples. One would expect a fungal cream to clear up a fungal infection completely, so I wonder if it is something different in your case.
Sometimes diabetes can cause a difficult to treat thrush, so you may need to be checked out for that too. I suggest you see your doctor again and if you are not satisfied then you could get a second opinion, either from a different GP or a specialist. It would be reassuring for you to have a firm diagnosis so that you can manage and cope with the condition better in the long term. There certainly may be an alternative cream to try that controls the symptoms more effectively. Other simple measures such as wearing cotton underwear, the avoidance of soaps and antihistamines can also help if you have not tried any of these already.
