Obsessed with” winning” after devalued and discarded, any advice for me?

I recognize these feelings and I am struggling badly not to act on them. I want to drive by her work every day to hopefully have the chance to walk past her and get her out of my system, but I don’t. I’ve obsessed for so long, I don’t know how to stop. I want to get my version out there, even though it doesn’t matter, but I’m constantly telling myself not to act on these impulses. I don’t know how to get over myself? It’s got nothing to do with her, it is all me at this point, and I don’t know how to stop giving a damn?

How do I get over myself?
