Do you think you deserve to be miserable for the choices you've made in the past?

I (20M) have made a lot of regretful choices in the past, and I sometimes think I deserve to be miserable for the rest of my life. But I always tell myself that I can start over, make amends, and change for the better. However, I would still feel like I deserve a lifetime of misery and regret for the choices I've made, and no matter how much effort I put in to be a different person, it would still tear me up.

Despite all of it though, I always have the strength to keep my head up high and tell myself that those feelings are just feelings that will come and go, and that they won't be my reality. Do you relate to what I said? If so, how much can you relate to it?
