If I realize someone isn't into me, my attraction towards them immediately disappears. So while I may not know exactly how this feels, I can say this. First off, alcohol and benzos can potentially exacerbate negative feelings and make you ruminate further, even it simultaneously helps at the same time. It's a very odd thing. However, If you've been binging on them, it will probably make you feel worse when you stop. So, that's a little tricky. Distractions are your best bet right now and also avoiding communication with that person and anything that reminds you of them. Choosing a new crush always works. I have actually done this before, except for a different reason. I had a crush on someone at my old job, but they left. So I literally just picked someone else, kind of just said, "eh, they'll do" and the strange thing was that the attraction started to grow quickly and intensely. It's kind of like when you develop a crush on someone just because you had a dream about them. Of course, I know simply picking a new crush is much easier said than done. I know none of this is good advice or very useful, but I'm sorry you're dealing with this and I hope this gets better for you.
