i'm about to ruin a good thing. im in a long distance relationship for 8 months with a real amazing guy. 

we have a 3 hour time difference  and everytime he goes to bed i do my usual bpd thing and freak out/threaten to break up with him/find reasons to keep him awake and its just getting worse.

what can i do to help control my behaviour? please no snarky replies. if it were as easy as "just dont be like that" i wouldnt be borderline :( 

thanks for your help
