Adhd making hifdh so unproductive

I have adhd and I'm unmedicated because medication does more harm than good for me.

I've been having this problem where I dedicate a lot of effort and I think a good amount of time to memorising and when it gets to my class, I don't remember anything.

My teacher is stated to get annoyed at me for my bad memory although i apologised many times and told her many times that I have a really bad memory. She is Egyptian living in Egypt and I don't think her English is at the level where I can explain to her that I have adhd and that I'm really trying but it's out of my hands.

I've tried multiple ways to memorise but I feel like my memory is getting worse and worse. Sometimes my teacher will correct me like if I've recited the wrong ayah she will recite the correct one for me to repeat but by the time she gets to the end of that ayah, I've already forgotten what she's said and she gets so frustrated.
