This isn’t me

There’s an entity of some sort living in me. It’s a parasite that craves attention and affection. It seeks it through others. I could be my normal self one second and then the next it takes over my being and it screams and cry’s out of desperation for someone, anyone. But of course no one will hear it. I have no choice but to ignore its needs. It overanalyzes every single word from anyone. It clings to anyone that cares even a little bit. It can’t stop thinking abt whoever my future partner will be. It needs constant reassurance, “I love you” daily and it craves for, “I care about you” nonstop. Without that, it panics. The worst part of all of this is that it’s not me. I mean, it’s gotta be me bc it’s me feeling this way but it’s not ME. The creature in me that is obsession strips me of my personality. It removes any amount of process I’ve made to becoming a better person by instead constantly wondering and worrying about what could possibly make me unlovable or unwanted. WHAT IS IT???? WHY DO I HAVE TO LOVE YOU MORE THAN YOU LOVE ME WHY DONT YOU LOVE ME LIKE I DO WHAT DID I DO OR WHAT DIDNT I DO I NEED THIS PLEASE PLEASE PLEASE!!!!! My soul feels empty, I need someone here like actually here with me. Or at least that’s what it convinced me I needed. How can I get rid of it. Please actually anyone how do I get rid of this parasite?
