Poems in my darkest times

Not mine! Dont know who wrote this

"One day you will realize how much you lost when you left me. I know you don't feel it now but give it time and you fucking will. And you won't see it coming, it will completely take you by surprise. My name will fill your lungs and you won't be able to breathe. Every word I said to you will echo through your veins. You will feel a huge void in your chest that no other girl will be able to fill. No one will love you the way I did. You will spend lots of time searching and searching to find that person- but you never will. That's when you'll realize how much you took me for granted and how badly you fucked up. You'll try to call, you'll try to see me, you'll try absolutely anything to get me back. But I'll refuse. I know I deserve better than you. I fucking loved you with all my heart and you treated me like I never meant anything to you at all. I know there is someone out there who will treat me like royalty and will treat me better than you were ever capable of."
