Does one who left fasting due to heart disease and claimed she was young have to make it up?

Question: When I was twenty-six years old, my mother told me, saying, "I was unable to let you fast because you were young, and there was thirst and severe heat." And when I got married, I was unable to teach you because you had an illness, and then you had heart disease, and I was unable to teach you. Now, you have a full month that you did not fast, and I now have two daughters, and my mother was unable to teach me until Allah healed me. I want the answer: Do I fast the month that I missed or not? Please inform me, may Allah reward you with good.
Answer: And upon you be peace and the mercy of Allah and His blessings. After that:
It is obligatory for you to fast all the days you broke your fast after you started menstruating, if menstruation began before you reached fifteen years of age. However, if menstruation began after that, it is obligatory for you to fast all the days of the month of Ramadan that passed for you after you completed fifteen years of age. In addition to fasting, you must feed a poor person for each day with half a sa' (a dry measure of about 3 kg) of the local staple food, such as dates, wheat, or rice, along with repentance to Allah (Glorified and Exalted is He) and frequent seeking of forgiveness.
May Allah guide everyone. And peace be upon you and the mercy of Allah and His blessings.
