it feels like i have to let them go but i can’t

my thoughts are screaming at me telling me that i dont want my relationship anymore and that i realized i lost feelings. i have a beautiful relationship of two years with a beautiful boy that loves me dearly and i deal with this thoughs for a year and a half. Im so scared it feels so real im scared i have changed and my last therapy session made it worse she basically told me i have to realise the thoughts are true and stop lying to myself. And made me think i am so scared and heartbroken bc i put high expectations on myslef to be with my boyfriend for all my life. Maybe i dont want to hurt him??? im always questioning my feelings for him 24/7 for over a year. I wm tierd

these days I feel particularly bad. I can't let the thoughts and those scenes be there without going deeper into it. Everything about my sister has become a trigger for me, and I have the impression that she "turns me on" and creates a big panic. I feel like I can't breathe because I don't know how to let it all go and I don't attach importance... 5 months of ERP and now this, I can't do it, I don't know it...and I don't know what else to do...

I’m trying to let them pass not engage nothing , trying to compusle but the thoughts won’t leave. My brain keeps telling me I should stab my dad for not asking if I’m okay after the death of my ex …
