I got blacklisted for cheating on an exam during Covid. I realize it was a mistake, but how can I make it right?

This is my first time posting on a Chambers thread. But I hope to get good advice. I want to start by saying I made a mistake, and I got caught. I was blacklisted for cheating on an exam by my university. The professor and I also had an out of class meeting. I admitted I had cheated. <br>It was during the height of the Covid-19 pandemic when I got my exam back. By then, I was already at home. I know it wasn't an excuse. But I wasn't thinking. This was a hard time for me. The math class I took was hard and I didn't study enough. My notes weren't good, so I had to open up another window and use Chegg. By the time I realized I had been caught and my professor had emailed me, I already knew it was over. By then, I was already feeling ashamed. I had made a mistake. I had already lost the class. So I admitted it, knowing I was done for. <br>It's been two years since then. I got my degree and graduated. I am sometimes reminded of it. I remember it on a daily basis. I already know it was a mistake. How can I fix it? How can I live with myself? I really am sorry for cheating. I want to believe in myself. How can I start to make it right?
