Can a person change despite the things they've done?

Can a person change? Can they be redeemed?

Truthfully, idk... tbh? Just stupid. Full of guilt. Exposing yourself to someone while you're in a relationship as they pressured you to and you couldn't get the nerve to say no cause you were scared to lose a friend? It's saddening. It was stupid. You regret it. But you told your SO the next day cause you couldn't keep it a secret. Cause you knew it was bad and you wished over and over again to change the past. To change that moment. You wished to change your past self from all of the things you became depressed over. You were clingy. You were scared. But you were scared to tell anyone your problems cause you didn't know who to turn to. You speak your side of the story to friends cause you can admit you were wrong. You can't find happiness cause you brand yourself as a cheater. You don't believe you should have been loved. Your recent relationship showed you, you did and that the person had believe you were able to change. Sharing passwords and showing messages and asking for advice. I'm not sure if it proves that you have changed, that you have been serious. But, you were happy when you didn't care about losing a friend when they did something to you. you had help. then again, you kept reminding yourself that you shouldn't be loved because of that moment. That moment you were a stupid, naive, lonely 17 year old who wanted nothing but friends. who trusted an adult and was scared to say no due to the pressure of "losing" them.

truthfully, I'm not sure if the answer is correct. I know you're hurting. I know you want to end it and start over. I'm not sure if others have similar experiences. But I know you wish people told you what you are. to hear them agree that you are what you believe.

I truly wish, that you find happiness. Even if you don't feel like you deserve it. I truly do wish you can finally have a peace of mind and be happy. You may not be able to change the past, but, you can better yourself. I wish I could tell you things. I wish I was better.

I love you.
