Why do I feel like this?

Every relationship I’ve ever been in I have always been the clingy type. I always wanna text, talk etc. like 24/7... I said that to say well recently I just gotten out of a relationship and like even though that love for him was still there, & still is.. I find myself trying to throw other men my way to I guess fill in the void I feel. It’s like I always need someone there. I hop out of one relationship & want to get right back in with someone else... I hate the thought of being single. I just feel like I need to be in a relationship to feel complete. I’m talking to a guy now & have been for a month (I’ve known him since high school though) We met in 2011. *I’m only 22 😕 we have been always just friends and recently, a month exactly we reconnected. Buttttt the thing is, i feel like I’m being that clingy girl again. I always wanna talk to him & etc but I try to give him his space... I don’t wanna mess this up 🤦🏾‍♀️ for example... yesterday, I didn’t talk to him all day and I felt some type of way about it, but I texted him last night & said”you full of sht” *b/c I didn’t hear from him all day... and he responded this morning and said that “Actually I’m not full of sht . Some days I be needing that . I don’t be trying to bother people and I be chilling.” & I just responded with “Gotcha”. .... sooo with all that being said, how do I go from clingy to giving him his space. It’s just so hard because I’m so used to always being with someone.. why do I feel like I need that male attention consistently? Am I crazy? Do I need help?
