How do I(17f)stop being so anxiously attached to my situationship? I’m neglecting my life.

I 17f have been talking to this guy everyday in a situationship. I like him so much, but I’ve become incredibly attached to the point where it’s impacting my daily life.I literally cannot stop talking to him to the point where I neglect my work, studies, and chores. I stay up late and sacrifice my sleep just to keep the conversation going. He isn't like this at all—if he has things to do, he easily puts his phone down and goes and does them.Because of the mismatched energy, I’ve started feeling really pathetic and lazy because I feel paralyzed and unable to get anything done when we aren't talking or when I'm waiting for a text. I know I have an anxious attachment style and emotional dependency happening here, but I don't know how to break the cycle.How do I get my power back, set boundaries for myself, and stop prioritizing him over my own life? Any advice would be appreciated.
