Tw/ self-harm

I used to go to a therapist about 6 months ago. And I had finally decided to talk with them about my Selfharm problem which was difficult for me.  So I ended up just telling them, and their only response was "Oh, I thought what you wanted to tell me was much worse". Idk if I'm just overreacting but it was just the hardest thing to tell them about that I almost started crying. Now it's harder for me to talk about depression and my mental health because of that reason. I also stopped going to appointments cause of that, it's been months, and It still hurts to think about it. Am I overreacting? :/
