What is the religious ruling on a girl with obsessive-compulsive disorder not fasting Ramadan, based on a doctor's recommendation to avoid conflict with medications and the worsening of her condition?

A sick person is permitted to break their fast and must make up for it later, as Allah Almighty says: "So whoever among you is ill or on a journey - then an equal number of other days." The illness that permits breaking the fast is one that intensifies with fasting, or if there is a fear that healing will be delayed because of it, or if it causes hardship. If the compulsive obsessive disorder reaches this level, such that it worsens with fasting, or fasting becomes difficult with it, or there is a fear of harm if medication is not taken during the day, then breaking the fast is permissible. However, if there is no hardship in fasting and medication can be taken after breaking the fast, then breaking the fast is not permissible. It is advisable to consult a trustworthy Muslim doctor regarding this matter.
