Can people suffering from NPD (or any other Cluster B personality disorder) be "good Christians"?

I'm struggling with the fear that me having and struggling with Narcissistic Personality Disorder (NPD) separates me from God because despite being self aware now and trying to work on myself in therapy, I'm still a mess.

I'm struggling with emotional empathy and I see most relationships as transactional, needing validation from others because I am lacking a stable sense of self or any inherent self worth so I fall apart when criticised. I can't help but think badly of my friends when they seek me out for help or when they are better than me and then I get very envious and feel contempt for them but I do my best not to show it because I know it's bad and sinful. I always help them but I can't tell whether it is because I want to maintain the image they have of me or because of my faith and that is painful because it's only thanks to God that I got through suicidal ideation and he keeps me on my path to get better and to not harm others like my parents when I have meltdowns.

Please do not judge me I'm trying to be better, pray for me and how do you think do people with a Cluster B personality disorder fit into christian communities and the kingdom of God?
