What is the ruling on increasing the number of fasting days as compensation for previous Ramadans, while being unsure of the correct number and fearing that the doubts might be mere delusions?

If a woman doubts the number of days she needs to make up, she must make up the days she doubts, because the original principle is that the debt remains obligatory for her, and doubt does not remove certainty. However, if she doubts whether she needs to make up any days at all, then nothing is required of her, because the original principle is the absolution of one’s responsibility. If she knows that she fasted what was due immediately after Ramadan, then she should dismiss doubts and illusions, because excessive thinking can lead to obsessive thoughts.
