A breast fungus can be persistent. While the treatment may be effective, the focus should be on prevention to avoid a recurrence. This includes measures like not wearing a tight bra, using an antifungal drying powder under the breast (especially on hot and humid days) and wearing light clothing to allow for good ventilation. Another point to take note of is that you should use any topical antifungal application (cream or gel) for at least 4 to 6 weeks after the infection resolves although you should not continue this if it is causing any skin irritation.

isn’t there some way that i can get rid of it for good?

Yes, your fungal infection will resolve with time. Usually an anti-fungal tablet should be used for up to one month or an anti-fungal cream/ointment should be used daily for up to 6 weeks in order to ensure that the fungus is eradicated and then the skin can heal. If you do not find any relief with your current prescription, it is important to return to your doctor and inform him accordingly. Avoid peeling or scratching the affected area as far as possible as it allows the infection to persist and spread by affecting the surrounding tissue integrity.
