Welcome to the forum Yumi...its so lovely to see you on here. Debbie has told me alot about you and the very special friendship you share. Im so sorry about the loss of your son to JHD, I can only imagine how scared you must be for your daughters future. I am not in the same situation as you, but I will offer you a few thoughts.
I think its really beautiful that your daughter and her boyfriend are so in love and talking about a future together...your family has been through so much, so to experience a happy relationship must be very wonderful for your daughter. It does sound like now would be a good time to talk about the HD and its risks for your daughter, so they can make informed choices about their future. Like Shy says, you may be suprised by what she already knows. Do you think she would talk to a genetic counselor?
I know when i was 19 i was probably feeling more like hiding from HD, but there are lots of young people who face this head on early in life and plan and prepare their futures, with children and with partners. Access to good information can help alot. Just because we are at risk of HD doesnt mean we dont have rights to have a happy and healthy relationship with someone. Your daughter, HD or not, deserves to be loved and to share the joys of life. From what you have shared it sounds like your biggest concern is her passing the gene on to her children. She needs to be given the opportunity to make informed choices about this...and to know all her options.
Do you feel she would be open to talking about it?
Ive been doing a fair amount of reading lately and Im working on a website for younger people. Does your daughter like to read? Scotland have a site for their young people, which Im drawing some information from. It has some information about being at risk, and options around children, which your daughter might benifit from reading. She is also more than welcome to join here and ask questions if she felt comfortable.
The information for your daughters age group is
http://www.hdscotland.org/youth/pages/young_adult_y18.html There may be some information which is not relevant given this was made in Scotland. But have a look and maybe you could print some of it out for her.
Take good care Yumi. Its really lovely to have you join us here. I hope it helps a little.
