Hello-  I would really love some advice/ support from the community. All day long I've been so anxious that I absolutely ruined things between the guy I was interested in and myself. I really liked him and I got complete tunnel vision about it. 

I feel like we just ended up talking too much, that I was trying to get serious too soon, and that I ruined it all by not being the chill cool girl. HOW do I come back from seeming like a clingy freak. Is there a comeback from this?
