Help me

I’m genuinely exhausted, both physically and mentally. No matter what I do, I can’t stop thinking about my ex. It’s like she’s stuck in my mind, and no amount of distractions can erase her presence. I’ve tried keeping myself busy, drowning myself in work, hobbies,anything to keep my mind off her—but nothing seems to help. The memories, the feelings, they all come rushing back when I least expect it. I don’t want to feel this way anymore, but I don’t know how to escape it. It’s tiring, and honestly, I just wish I could let go.
