<human>: Can you summarize the given text in a few sentences?

Okay quick background into our relationship, Me (M/17) and my girlfriend (F/16) have been together for 9 months. 
This is an incredibly long amount of time for me as I've not dated someone this long, I love this girl to pieces. But, I do have some problems, and one of the main ones is that our relationship has never moved on from the "obsessed honey moon love" cliche. I have underlying symptoms of borderline personality disorder, it really does effect our relationship majorly. As it causes me to switch between being madly in love to hating her etc. Causes me to be jealous over nothing. Causes me to overthink and make things up. And now me and her have gotta go on separate vacations for two weeks with NO contact whatsoever. So how can I survive this without her?!?!
<bot>: Going on vacation for two weeks, can't contact my girlfriend of nine months, got some problems with thought processes, how do I survive?
