Don't think much of the online testing .. I took that test and got a severe result... The thing is Bipolar people seem to have a few traits of bpd .. Don't sweat it.. Your in a bad spot right now.. But it is going to get better. You are going to cycle out of it, It always cycles.
Try to find things to distract yourself with... a movie, a book, puzzle,loads of online silly games, puzzels, or any mindless type activity, and of course keep posting here
