Why I’m I still getting anxious about this a few months after?

This has been going on for a while now and I want to get to the bottom of this. I have had a crush on this celebrity for a while now. Every time I see him with a girl I would actually get extremely anxious like my hands will start to sweat, I will find it a bit hard to breath and feel like I’m about to vomit. When my sister would say he was attractive the same thing will happen expect 3x as worst. I know this because I would stay up late at night thinking about it and unable to sleep. Currently it has gotten better, I believe this is because I don’t find him attractive anymore and don’t care about him. However I still seem to get these feelings when my sister says he is attractive. I know when this first happened I was dealing with some generalized anxiety but now I think I have the generalized anxiety under control. Why I’m I still getting these feelings when she says he is attractive even though I don’t like him anymore?
