Serious Anxiety over boys

I recently got out of a pretty bad 7 year relationship from when I was 15, to now, aged 22. And I am just CONSTANTLY anxious about boys. I’m a flirt, always have been, and I enjoy talking to lots of guys at once, and to be honest, I’m enjoying sleeping around a bit too. But I’m only 6 months out of this big relationship and I’m already falling for 2 of the guys, to the point where I KNOW I’m being stupid, and stressing over every little conversation, reading way too much into everything

Does anyone have any advice? I’ve never really dealt with this before and it’s effecting me on a daily basis. I hate it 😔
