Personality disorders are particularly difficult to diagnose, often requiring many consults, followed by extensive Psychological testing along with clinical judgement. No, the disorder will not come to your children through inheritance. They may have it independent of the factor, but there is little evidence for heritability of personality disorders. You must also understand that with personality disorders, they are not treated, but managed. Your personality cannot be changed completely. However, you can be more aware of your own reactions to your surroundings, and consequently, adopt appropriate modifications to your behaviour. I recommend going through Psychotherapy with a Psychologist for the same. Good luck.
