Borderline personality disorder treatment and support?

I am currently undiagnosed, but 100% positive i have a borderline personality disorder, the low functioning kind at that. Im only 19 and im getting increasingly worse, its pretty much debilitating in almost every aspect of my life. i cant keep a job, i cant maintain any friendships or relationships and im alienating my family. i can recognize my symptoms after the fact, but im not sure how to seek help or correct them myself. i live in a relatively small city and there isn't many options for psychiatric help, even if they were i couldn't financially afford to take advantage of such services. iv been reading as much as i can about this disorder but im finding very little useful information. id like to know from other people suffering with this what has helped, what techniques i might be able to try, or where i can find some affordable help or support. i feel like im out of control, alone and im not sure how much longer i can live like this. whats most frustrating is that i can tell when im being irrational or crazy but i cant help it, i cant seem to change my self or my behavior and reactions to situations that come along with everyday living
