My vacation that I have to go with family is coming up in three days, its a week long vacation out of state. 

The day I get back is the morning he leaves for 2 weeks in another state a couple thousand or so miles away..

Total gives us 3 weeks without being with each other physically. I don't know what to do or how to handle myself since I've never been apart from my favorite person for this long.

 I've been apart from someone that I was with for 5 days but that didn't go too well on my end because  it triggered a week long episode along with panic/anxiety attacks, rage episodes, and the gods name it. 

I've been better with my BPD as time goes on and I get older but this is new to me and honestly I'm afraid and mostly sad about it. 

Half of me wants to go full on bawling crying and the other half is scared of how things will go with the next three weeks ahead. 

I'd truly appreciate some help or advice in dealing with situations like this, so I can better myself for the future and prepare myself for this coming up.
