Depressed because of my exes I can't move on

Hey everyone, I’ve been struggling with depression and anxiety because of my ex, and I can’t focus on anything. I don’t know what to do anymore. Whenever I try to move on, some negative people keep mentioning my ex and mocking me. I feel broken right now, and I can’t live my life freely. I feel like people are targeting me and ruining my reputation without caring about my feelings. I thought I had moved on, but now I feel like a rotten fruit that can never become fresh again. I’ve even had panic attacks, and I feel like I’ve lost my innocent self. I can’t focus on anything, and I feel emotionally exhausted.
