I am now aware that disrespecting my parents is a major sin in Islam and if you do it you will not enter paradise and all your duas and prayers will not be accepted.
However, when I was younger, I did not know that this sin had these major consequences, so I sometimes would disrespect my parents or talk back to them in a rude way. Does that mean that all of my previous prayers and duas are not accepted?
Sometimes I do things that might slightly annoy them, or I might shout a bit when I am very angry when they are very unfair to me, but my parents are not mad at me, and I did it out of control and much awareness, and later everyone forgets about it and it is no big deal. Do I still have to ask for and pray for forgiveness from Allah for this disrespect?
I am confused about how this works. Does it mean that every time I might disrespect, my prayer and dua stops being accepted?
