Repentance and taking the means to right wrongs
Dear questioner,
May Allah bless you and increase you in good.
Yes, the repentance will count. However, you are obliged to make up all missed fasts you mentioned. Your repentance is sound.
Conditions of repentance
(1) Sincere remorse for the sin
(2) Immediately leaving the sin
(3) Firm resolve never to repeat the sin
[Nawawi, Riyad al-Salihin]
It is recommended to make them up as soon as one can. However, It is not an obligation to make them all up immediately. [Maydani, al-Lubab fi Sharh al-Kitab]
Suggestion for a schedule to make up fasts
I would suggest you use shorter days in the winters to make them up quickly without a lot of difficulty depending on your situation. Another suggestion is to fast on Mondays and Thursdays, and you can make them up in just two years roughly. Insha`Allah, you will be able to make them up soon.
May Allah grant you success.
[Imam] Yama Niazi
