Bpd and selfishness

I feel like im losing my mind… is it normal to feel selfish with bpd. I constantly feel like I'm a really selfish person because sometime I'm really in my head and I only think about myself and my mental condition but at the same time I don't think people realise it's a personality to sort a side affects my personality and everything I do in I just don't know what to do. Is anyone else deal with this? I just realised this because when my boyfriend was complaining about his sickness i could only think about my BPD it just made me feel like really on the undervalued as a person. I don't know why.
