how do you mend a relationship when you're constantly making mistakes?

comments are encouraged as i need someone to give me some advice.

so i have this teacher. and before you think anything bad, i'm not being groomed or anything. however, i've had this teacher for 2 years now and our relationship has deteriorated.

when i joined the school last year i was quite shy during lessons and i still am sometimes. during the year i slowly would be more expressive and we had created a great bond (as far as teacher-students bonds can go tbh). i continued with the subject, and this current year i have her as my teacher. this is where things got bad.

i had taken advantage of this teacher as she was nice to her pupils. i wouldn't listen in her lessons, and never take part. i would talk back. i would judge. i would be as rude as i could be. at the end of almost every lesson she would pull me behind telling me about how rude i was being. this never really registered in my brain until recently.

we were put into groups we would have for the rest of the year. i was with one of my friends, a girl i knew from a few years back, and two other girls. me and my friend would make looks and overall act "bitchy". still i never realised how i acted and how it affected others in the group.

until me and my friend got pulled over by my teacher.

i had sort of realised how rude i was being. but this pull over thing would become constant, and i never really understood why. i was being too arrogant to realise i am the bad person, and would rather blame it on the teacher. i have had to send her multiple emails apologising about my behaviour. she has given me second chances time after time again.

i took it too far.

a few days ago, i saw one of my teachers devises laying on a table. i breached her privacy by taking a photo. she pulled me over the next day to tell me about how i have taken it too far and have violated her privacy. there was way more things she said.

i apologised in person and via email yet no reply so far. i just want to know the answer. what do i do?
