Do you ever feel that you need to tell your thoughts to someone you trust to feel better? Like a confession or something

I made a post earlier today about my past and things that happened and maybe I didn’t phrase it really in the best way haha :’)) so I’ll try and make it shorter. February has been complicated for me and recently. First my mental health was bad because of studies but I had this thought regarding my past that was a little tempting and led me to spiral on about my past, I gave into it and that really took me for a whole spin. I’ve started to open up about things that I never thought I would talk about and even slowly opening up to my therapist. These things happened in childhood and I mimicked actions I saw at a young age ( despite these things happening, it was only just one side of my childhood ) and even though it’s still not easy for me to deal with it, I often have the urge to confess and fear that it’s my intuition telling me to confess and if I don’t, something bad is going to happen or I’m a bad person. I’ve talked about my story to someone in a detailed way and to my therapist briefly and she understood and treated me with kindness but these thoughts still linger. Sometimes it gets to a point where I have the thought briefly telling me negative things but it doesn’t focus on the good things that happened and how I’ve learned and not repeated the action. It just focuses on the bad and when I just pause , it goes silent and keeps quiet, I realise that it’s all just thoughts.

Why why WHY do I feel the need to constantly overshare?! It’s making me feel guilty af! If my boyfriend tells me something in confidence but my ocd twists what’s said into some crazy big problem I feel the need to run to my mom for reassurance, it’s getting to the point where he doesn’t trust me not to talk about stuff and I don’t want him to feel like that obviously!! But it’s like I can’t stop! Does anyone else have that? How do you stop it?

I have this strong yearning to tell my mother all my thoughts and what I go through on a daily basis but then I get scared of what she'll think of me or that she'll worry even more and feel like it's her fault. I just want someone to understand what im going through but whenever I even begin to explain my thoughts to my therapist, she doesn't really get it and today it feels like no one ever will. like I try to make my therapist understand and bless her heart, she's super compassionate and understands how much pain it causes me but beyond that, it still feels like im not able to fully convey it. I'm sure this is something many people can relate to, but still. I feel alone.
