real event gotten so bad

Please help, idk what to do, my reocd got me spiraling for weeks and i can't calm myself down. I was recently diagnosed with ocd (i've always suspected that i had it) and moderate depressive episode. i confessed to my mom and she said that it's not that bad and that she doesn't view me as a horrible person, after that i confessed to my therapist and told her everything, she thinks that i'm blowing it out of proportion. I asked her at least 4-5 times if she view me as a bad person and if she disappointed in me, she said no, she said people were confessing much worse stuff to her, but i can't stop freaking out, i feel horrible, i feel like i ruined my own life and there's nothing to be do about it. i can't stop thinking about it, i can't stop blaming myself. i feel like there's only one outcome for me left.
