Help getting over a heartbreak

Hi, five months ago I got broke up with from a guy I was with for five years. And I still feel just as hurt and sad as I did when it first happened. I’ve been really struggling for five months and i feel completely stuck. I cannot let go of him no matter how hard I try. I feel so connected to him still. And it’s driving me insane. I think about him all day everyday. There is a constantly ache in my chest because I lost him. I feel like he was my other half and now it feels like I’m missing a part of me. I’m basically desperate to feel better and get over him. I need to disconnect from him. So I’ve recently started getting into spirituality like crystals and energy work. I don’t know a whole lot about it, especially energy work. Like… how do you do it? I guess I’m asking for a little guidance from you guys who know so much more than I do. What should I be working on and doing in order to heal? I have some crystals I got a couple years ago that I tried to mediate with and am keeping them under my pillow. I also bought moldavite which I am going to wire wrap into a ring to wear during the day. I just want to feel better and I definitely need to get more in touch with myself and start healing.
