Do bpd's feel upset when they don't feel love anymore?

I have been diagnosed with traits of bpd and have rarely felt love for my boyfriend for nearly a year. I am completely heartbroken because this happened overnight during a very stressful period(i'd relocated to be with him, hated my new job, found it hard to fit in down here and had a physical illness to contend with). Before I 'switched' I began to feel terrified that he'd leave me, jealous of ex's etc and the BAM I woke up and no longer loved him.
I have been severely depressed ever since and now even find it hard to feel things for other people-family and friends.
I do feel love at times and when I do, I feel different about everything-i feel ok about myself and confident etc. When I feel nothing, I feel absolutely terrible and want to die.
I've heard that some people with bpd fall in love quickly and out of love just as quick. But do they feel upset and want to love that person again??
Another confusion to this is even tho I feel nothing, I get jealous and fear him leaving me?!
Please help someone. I can't stop crying:-(

Hi,

Are you sure that the depression has nothing to do with your feelings for your partner? They might very well be inter-related and, therefore, you might still love him but the depression is clouding it.
