hey roman,
i would also like to bring borderline up too... when i was 18 (i'm now 20), i also thought there was no way in hell i would have borderline, but later on i can see how that fits me, and is easily confused with bipolar.
but, it doesn't matter which diagnosis you have, it's just tags and labels for the professionals to use. bipolar and borderline have a lot of symptoms in common and some bipolars and borderliners have same types of medication. (mood stabilizers, antipsychotics etc, these days they'll use anything)
if you think you could benefit from meds, and the reasons for which you are not on any right now would allow you to - try it. but also remember that if the meds make you feel bad you can always ask for a change and that is your right. (cynical me talking who was forced to take medication that made me feel terrible)
also give psychotherapy a thought. maybe seeing a psych nurse would help you too? you're in college right? sorry i haven't read all the posts, been a little out there as well, but if you have a school counselor (psychologist? whatever they're called in the states? i'm in europe so i wouldn't know, but when i went to high school i saw a school psychologist and it was very helpful) try to get a hold of them and see if it could work out.
hope any of this was helpful / got you any new ideas, you deserve help and should imho look for it before you're in the eye of the storm.
