My struggle with harmful people

Assalamu alaikum everyone, I want to open up about the tough times I've had dealing with dishonest and hurtful people. Alhamdulillah, I’m no longer in touch with those who robbed me of my peace, but I’m still on sleeping pills and antidepressants because of how hard it’s been. A few years back, I was really naive and innocent, struggling with serious sleep and eating issues during my first year of college. It messed with my mind, and sadly, some people took advantage of that. I faced stalking, humiliation, and being targeted in group chats-just one heartbreaking experience after another. Now I feel so low, and I miss the joyful, carefree person I once was. Friends used to call me a ray of sunshine, but now I feel heavy all the time. It’s like they drained my positive energy. They kept calling me innocent in a mocking way and wouldn’t stop bothering me. I really need some reassurance and advice. Please, keep me in your du’as.
