First of all.. that's all of us. Don't let anyone kid you... we've all made mistakes. Secondly... God made you for love and He's aware of your mistakes. True, He wants repentance and improvement, but He is not seeking self-loathing.

I feel like it's easier said than done. I can tell myself that I have learned from my mistakes. I can tell myself that they're in the past but that doesn't change the guilt I feel inside. I just want to be able to let it go and fully enjoy life for what it is. I don't want to keep letting my sadness hold me back.

I am going thru this myself. I feel as though my mind is haunted by the past, my past choices, the thoughts of wanting my marriage to work, but feeling extremely haunted in the sense that ill never feel comfortable again with the idea of US (my wife and i), never feel comfortable with myself as a person. I feel like i just want to give up on my marriage. I have too many trust issues. My wife and I are two entirely different people. I feel like i have put her thru so much and i dont know how to live with it anymore. She says she loves me etc and wants us to work etc and yet she is prepared for the idea that it might not work, after 10 years. Feeling lonely and heartbroken...

Realize everyone makes mistakes and try to improve and grow from those regrets, never stay the same. If you are aren't moving forward, you are going back and no one wants to live in the past.

The moment you realize it, you have two ways to go; 1), Feel pity about it and be hard on your self. 2), Be better person, learn from it and do good around by being helpful.

It's hard but you need to draw a line between then and now and declare the past over with.

You can't change the past. Try not to repeat the same. You can be a better person. Good luck :)

I know it is hard, but done is done. You honor your past by learning from your mistakes and living better. In Buddhism it is called the second arrow. The first arrow is you make a mistake, the second arrow is you condemn yourself for the mistake. The second arrow only serves to keep you from doing better and having peace.

If you acknowledge what you did was wrong, and you accept full responsibility for your actions, well, you ARE a good person. I did some pretty messed up things in 2016 but I know what I did was wrong, and I'm working towards never doing that ever again. You can do the same.

Mistakes are how you learn. Preferably other peoples mistakes, but often your own. Everybody makes them. Acknowledge that you've effed up, learn from the experience and don't do it again...!
The fact that you realize than you have made mistakes means that you are 3/4 the way there...

You should learn and try not to make the same mistakes again. We are all humans. None of us are perfect.

Forgiving myself is even easier than forgiving others. I know I'm flawed and that makes it easy.

All good questions, for which I have no answers at the moment.
