For the longest time I struggled with Praying. I had difficulty with keeping wudu. Sometimes I could keep it sometimes I could not. I found it extremely stressful so i stopped praying for 2-4 years. Then later I read that if you struggle with keeping wudu you can just do it once and then pray. Since then I have prayed everyday. My question is do I have to make up the prayers i missed?
If you're not a woman, then the simple answer is Yes, I guess no matter which school of thought you want answers from.
I don't think there will be a difference in opinions in between schools, cuz this matter is a matter of Fard (compulsory deeds to be performed no matter what).
If you're a woman, then you don't have to repeat the prayers (Salah) which you missed during menses. (But you need to repeat the fasts though which you missed during menses in case it is Ramdan).
May the creator guide us all.
