Nerves and unanswered questions

So I resently found out that my mother has a hereditary version of liver failure(not the version caused by lifestyle) and its passed on to the females on her side of the family... I worry about it so much... Her sister died from it, her mom died from it, and now at around the same age she is too... Am I doomed? I want to have kids but if I'm a carrier or have that gene idk what I'd do... I feel so torn apart. My husband and I have been married 5months and together for nine years... and I know he doesn't care whether we adopt or have our own, but I keep reading about the fact that it's not avoidable If its hereditary in nearly all cases...im having what I guess would be my midlife crisis if I carry that gene.... My mom is barely over 50...I'm so nervous about it I haven't been able to get up the nerve to get the tests done to see if I carry the gene...
