I’ve made ONE terrible terrible mistake behind the others that’ll haunt me for a long time. I’m seeking therapy about it , but I’m afraid that the damage is done. I can’t go into details , but let’s just say I never did it again. I was even a victim at a very young age , probably around 4 I think or 5 idk I was fucking young. I’m disgusted and ashamed. How can I move on from it ? 
What’s the key? 
Am I irredeemable if I never made that same mistake again?

My other mistakes this past year was cheating on my ex with her bestfriend. It sucked because she was sweet at first and she let me live with her when i had no place to go but she started staying home and left me to take a lot of responsibility. We were barely 20 btw. Her best friend told me she didn’t like how she treated me and idk if that was her way of trying to manipulate me into going through with our cheating, but part of me wants to regret it but if I’m being honest she was more my type. Shared the same scars and it sucked because we were alike but different. Now my ex still wants to works things out but if I’m being honest I’m too immature and still have issues for a healthy relationship. I need to take responsibility but I don’t trust my therapist or myself.
